Question

What will be the volume of 25cm3 of gas if temperature is increas from 20°at constant pressure

Answer 1

Answer:

Increases

Explanation:

We will use Charles law for solving this type of question

V1/T1=V2/T2

Note= first change the degree to k i.e. 20+273= 293k

Lets suppose we say that the temperature is increased by 10o

The new temperature is, 303k

Convert the volume in dm3= 25/1000 = 0.025 dm3

Now put the values in Charles law

V1/T1=V2/T2

0.025/293 = v2/303

303 x 0.025 / 293 = v2

0.026 dm3 =v2

Or

0.026 x 1000 = 26 cm3
