Plz solve it quickly​

Answer 1

Answer:

option D) -213°C

Explanation:

PV=nRT

For constant P & n,

V is proportional to T

=> V(1) ÷ V(2) = T(1) ÷ T(2)

given V(1) = V

V(2) = V - (80/100)V = 1/5 V

T(1) = 27+273 = 300K

T(2) = T (let)

=> V ÷ (1/5)V = 300/T

=> 5 = 300/T

=> T = 300/5 = 60K

T = 60K

T = ( 60-273 ) °C

=> T = -213°C
