Anormal breath of air is about 1.00 l. if the air is drawn in at 18.0 ∘c and is warmed to 35.0 ∘c, what will be the new volume of the air? assume that the pressure and amount of the gas remain constant.

The new volume of the air is 1.05 liters.

Explanation:

By Charles's law, we can make a relation between temperature and volume, where the volume of a gas (always in constant pressure) is directly proportional to its absolute temperature (T° in K)

So, when the temperature is increasing, volume increases

and when the temperature decreases, volume decreases.

V1/T1 = V2/T2

T° in K = T ° in C + 273

18°C + 273 = 291 K

35°C + 273 =308 K

1 L/291K = V2/308K

(1L /291K). 308K = V2

1.05 L = V2

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
