Question

1). A container was kept at a pressure of 20.2 atm and a temperature of 13.6°C. What would be the new temperature, in Kelvin, if the pressure was decreased to 7.9 atm?2). A car tire is at 40°C and has a pressure of 1 atm. If the temperature is lowered by 10°C, then what will be the effect on the pressure of the tire?

Answer 1

answer and explanation

we first nee to convert the temperature to Kalvin and te do the clalculation

13.6 + 273.15 =286.75K

we know that P1/T1 = P2/T2

so to find the new temperature we simply say

T2 = P2T1/P1

= (7.9 x286.75)/20.2

= 112.14K

the new temp will be 112.14K
