Gas laws calculations quiz
1. a gas has a volume of 3 lat 21 c, if the gas is heater to 100 °c, what is the new volume?

V₂ =  3.8 L

Explanation:

Given data:

Initial volume = 3 L

Initial temperature = 21°C

Final temperature = 100°C

Final volume = ?

Solution:

( 21=273 = 294 K)

(100+273 = 373 k)

According to charle's law,

V₁/T₁ = V₂/T₂

V₂ = V₁T₂/T₁

V₂ = 3 L× 373 K/ 294 K

V₂ = 1119 L. K / 294 K

V₂ =  3.8 L

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
