Charles’ law explains which of these phenomena?

a. why a balloon deflates when the air around it cools b. why solids require heat in order to change into gases c. why the pressure of a gas increases when volume decreases d. why some gases only react with each other at high temperatures

The correct answer is A. why a balloon deflates when the air around it cools

Explanation:

According to Charles' law, in gases the temperature and volume are related, in this way the volume of a gas increases if these are heated or if the temperature rises and in the same way the volume of a gas decreases as the temperature falls. This law explains "why a balloon deflates when the air around it cools" because this shows the gas in the balloon reduces its volume and therefore deflates when the temperature decreases, which shows the relationship between temperature and volume described in Charles' law.

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
