Arigid canister with a radius of 5 in and a height of 10 in is filled with air. the initial pressure and temperature of air in the canister are 14.7 psi and 70 °f respectively. later, the canister is heated such that the air pressure inside it, increases to 30 psi. calculate the total heat transferred in [btu] to air in the canister during this process.

1.458 Btu

Explanation:

Given

radius of canister

Height of canister

Initial pressure

Initia ltemprature

Final pressure

as canister is rigid therefore change in volume is zero

therefore

=

=

volume of canister=

                               =

volume of canister=12872,038.8

now calculating mass of air

PV=mRT

substituting values

m=21.0192 gm

Therefore heat transferred =

                                             =

                                             =1539.052J=1.458Btu

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.
