Question

Increase The Volume Of 80 Cm Cube Of Gas By 20 Percent Ad Temperature Is 25 C At Constat P

Answer 1

Hii Dear,

I suppose you're asking the final temperature.

◆ Answer -

T2 = 84.6 ℃

● Explanation -

# Given -

V1 = 80 cm^3

∆V/V1 = 20 %

T1 = 25 ℃ = 298 K

# Solution -

Final volume is calculated as -

V2 = V1 × (100+20)/100

V2 = 1.2 V1

According to Charles law -

V1 / V2 = T1 / T2

V1 / 1.2V1 = 298 / T2

T2 = 298 × 1.2

T2 = 357.8 K

T2 = 84.6 ℃

Therefore, final temperature of the gas will be 84.6 ℃.

Thanks dear...
