Answer:
The heat required to raise the temperature Q = 78.7 J
Explanation:
Given data
Volume = 5 liter = 0.005
Pressure = 0.205 bar = 20.5 k pa
Initial temperature = 300 K
Final temperature = 340 K
specific heat = 0.473
Gas constant R = 0.082
From the ideal gas equation
= m R
Put all the values in above formula we get,
⇒ 20.5 × 0.005 = m × 0.082 × 300
⇒ m = 0.00416 kg
Heat required Q = m × C × ( )
⇒ Q = 0.00416 × 0.473 × ( 340 - 300 )
⇒ Q = 0.0787 KJ
⇒ Q = 78.7 J
This is the heat required to raise the temperature.
