Question
State the units in which the characteristic gas constant R is usually expressed
3.
and explain why it has not the same value for all gases. In an experiment to
determine specific heat capacity of the air at constant pressure, 50 g of air at
constant pressure were heated from 14°C to 74 °C during the period 300 seconds
by continuous electric heating method. The average value of the power used by
heater was 10.04 Watts. Use the information to find the value of the specific heat
capacity of air at constant pressure. Hence find a- the value of the characteristic
gas constant R b-the density of the air at 0°C and 0.1 MPa. y =1.4
