Answer:
363.6 K
Step-by-step explanation:
To solve this problem we will use Charles law equation i.e,
V1/T1 = V2/T2
Given data
V1= 350 mL
T1= 45.0 °C
V2= 400.0 mL
T2=?
First of all we will convert the temperature into kelvin because the kelvin is an absolute scale of temperature.
T1= 45.0+ 273.15 = 318.15 K
Now we will put the values in equation
350 mL / 318 K = 400 mL / V2
V2= 400 mL × 318.15 K / 350 mL
V2= 363.6 K
We can see that by increasing the temperature volume of given gas is also increases. we conclude that volume and temperature are directly proportional to each other. It is also confirmed by the Charles law.
“ The volume of given mass of a gas at a constant pressure is directly proportional to the absolute temperature ”
