Chemia: Tlenek Węgla (IV)

Dwutlenek węgla stanowi około 0,04% objętościowych w powietrzu

Źródła dwutlenku węgla mogą być ze źródeł naturalnych n.p. spalanie i wybuchy wulkanów, procesy fermentacji, butwienia i źródeł antropogenicznych (wytworzonych przez człowieka) transport i przemysł i oddychanie.

Właściwości fizyczne:

• Gaz
• Bezbarwny
• Dobrze rozpuszcza się w wodzie
• Gęstość około 1,5 raza większa od powietrza

Właściwości chemiczne:

• Tlenek niemetalu
• Bezwonny
• Nie pali się i nie podtrzymuje spalania
• Powoduje mętnienie wody wapiennej, gdyż z nią reaguje

Zastosowania dwutlenku węgla: 

• przemysł spożywczy - mrożenie, schładzanie i konserwacja  żywności; produkcja cukru i napojów gazowanych 
• ogrodnictwo - w chłodniach
• medycyna - krioterapia
• ochrona przeciwpożarowa - w gaśnicach śniegowych

Suchy lód - Dwutlenek węgla w stanie stałym (-78ºC)
Woda wapienna - odczynnik umożliwiający identyfikację dwutlenku węgla. woda wapienna mętnieje pod wpływem dwutlenku węgla.

Fizyka: Masa i Ciężar

Masa - wielkość fizyczna określająca ilość substancji. Ta sama cecha ciała decyduje o jego ciężarze. Jednostką masy jest kilogram ( 1kg ).

Ciężar ( siała grawitacji ) - siła, z jaką Ziemia przyciąga ciało.

Znając masę ciała, możesz obliczyć jego ciężar według wzoru: 

Fg = mg

• Fg - ciężar ciała
• m - masa ciała
• g - stały współczynnik zwany przyspieszeniem ziemskim

DIY Centrifuge Training Machine

First thing in the morning I had computer coding class. This time we were only building Mindstrom.

Looking for a LEGO piece

Let's build!

Later we had lunch together, I was in charge of preparing it - we made spaghetti á la carbonarra and mushroom soup.

Let's start

DONE! DIG IN!

After lunch we had science class it was about centrifuge training machines and G-Force.
As you know astronauts must prepare themselves for the very strong G-Force acting upon them when they break from the Earth´s gravity or enter it back.

We learned how the centrifuge training machines work and we also made a small DIY model of the machine.

Here is my model:

Take a look how it works:

BANANA MUFFINS

So this time I am going to write about baking, YAY!

Ok, so I made these muffins a few days ago and now I am going to share with you the recipe.

Ingredients:

• 1 egg
• 1 tsp. of baking soda
• pinch of salt
• you can add chopped walnuts
• you can add cinnamon too 

1. Preheat the oven to 150C (around 300F)
2. Line the muffin baking tray with muffin cups.
3. After peeling the bananas, mash them well (with a fork or a blender).
4. Mix the mashed bananas with sugar, all purpose flour, salt and baking soda. Add an egg (and cinnamon if you choose).
5. Melt the butter and combine it with the mixture.
6. Fill the prepared muffin cups with the dough mixture (like on the photo below).
7. Bake for 30-40 minutes or until the stick comes out dry.

BON APPETITE! ;)

10 reasons to play LEGO Marvel Super Heroes

Ok, so my Mom told me that if I want to play Lego Marvel Superheroes I need to write 10 reasons why she should let me play, so here they are:

1. For the whole week I was banned from computer so I was waiting for the whole week to play.
2. I didn't play Lego M.S. for a long time.
3. I tried to finish all my homework yesterday (because there was a slight change of plans this week -  I got a modeling job ... and other stuff).
4. I really like this game (really, really) oh! and FYI I got this game from my Polish Grandma.
5. And altogether I was quite a "good boy" this week.
6. Wait it is not done yet oh noooooo!, so ... Owen (my best friend) can not talk on hangout tonight sooooo I will be playing by myself.
7. Ahhhhhhhhhh ... don't know ... golly! ... noooooooooooooooo!
8. Ok, next - I played on the saxophone and piano.
9. I really need to finish a mission in the game.
10. Last one aaaaaaa, so I was good today?

Wait you say line number 7 is not a reason good enough.

Ok, so if you say that line 7 is not good then here is another reason - I wrote my blog post today - Yay!

My Christmas in Taiwan

Christmas is over (and even New Years)  but I want to write about what I did on Christmas .
Did you know that in Taiwan Christmas is not a holiday?
Every has to go work or to school. This year even my Dad had to go to office .
Polish Christmas lasts three days, from Christmas Eve (Wigilia) to December 26 .
For Wigilia we prepare 12 different dishes. Among others there are: my favorite wild mushroom soup (or  barszcz - beetroot soup), fish, pierogi (dumplings with sauerkraut and mushrooms) and many cakes. We don't eat meat on Wigilia.

A HUGE salmon

Pierogi, I made them

Polish potato-egg salad, Mom's specialty. 

Walnut cake (no flour!)

Gingerbread cookies I made

 
But before we start eating we share Oplatek  (Christmas wafer) wishing everybody all the best.

Oplatek from Poland  

After dinner it's time to open presents. That's of course what I was waiting for.

What is it ?!

A Chromebook13!!!!!!!!!!!!!!!

Two Jazz CD's Charlie Parker an Current Hits In Bossa!

After all the presents are have been open we go to church for midnight mass fortunately in Taiwan it is at 10p.m.

I was serving at the Mass

On the evening of Christmas day we went to my friend Owen's Christmas party. There were many people, that we did not know, at the party. I played Wii with other kids.

On the second day of Christmas my grandfather and grandmother from Taiwan came.

All Saints Day at Powązki

Polish people celebrate All Saints Day on November 1st. It's a very important holiday.

While we were in Poland we went to the cemetery three times. Few days before All Saints Day we went to clean the graves in the Powązki cemetery (which is the oldest cemetery in Warsaw). Here are some photos of our family graves:

Before cleaning

After cleaning

My great-grandmother and
great-great-grandmother's grave

Most of the alleys in the cemetery looked like this:

On All Saints Day we went to the Powązki cemetery at night. It was even more beautiful than during the day. There loads of people. All the graves had candles and lots of flowers on them. There was the nice candle smell in the air.  It was quite cold, but not as cold as in previous years.

Look how nice it is now!

Graves of famous people, like this singer, had  l o a d s  of lights!

And more!!!!!!!

On November 2nd is All Souls Day. On that day one should also go visit more graves. We went to another cemetery, Powązki Military Cemetery. Many polititians, soldiers and famous people are buried there. 

I was most interested in seeing the graves of young people who died during Warsaw Uprising in 1944. I found the grave of the author of one of my favourite books "Kamienie na Szaniec", Aleksander Kamiński. There were also graves of those who were portrayed in that book, Alek, Zośka, Rudy and other  Warsaw Uprising heros.

Graves of those who lost their lives in World War II.

The grave of the author of the book.

The graves of Zośka, Alek and Rudy.

Polish cemeteries are so different to the Taiwanese ones and people visit them more often than in Taiwan. What do you think about Powązki cemetery?
