As a debate kid, the purpose of the source is to provide evidence on a point. You are proving that your point matters by giving a piece of evidence that supports what you’re trying to say. Without evidence your claim isn’t impactful.

Calculate the number of grams of oxygen gas in a 24L container at STP
romanna [79]

There are 34 g of oxygen in the container.

We can use the<em> Ideal Gas Law</em> to solve this problem.

pV = nRT

But n = \frac{m}{M}, so

pV = \frac{m}{M}RT and

m = \frac{pVM}{RT}\\

STP is 0 °C and 1 bar, so

m = \frac{\text{1 bar} \times \text{24 L} \times 32.00 \text{ g}\cdot\text{mol}^{-1}}{\text{0.083 14 } \text{bar}\cdot\text{L}\cdot\text{K}^{-1}\text{mol}^{-1}\times\text{273.15 K} } = \textbf{34 g}\\

To cook food, a microwave oven converts electrical energy into ________ energy. A) electromagnetic B) heat C) mechanical D) nucl
Mariana [72]

Answer: Option (B) is the correct answer.

Explanation:

When we heat food in a microwave then the electrical energy of microwave produces microwaves which are also part of electromagnetic spectrum.

These microwaves are absorbed by food and as a result microwaves change into heat energy. Therefore, food becomes hot.

Thus, we can conclude that to cook food, a microwave oven converts electrical energy into heat energy.
