Convert the following pressure value into Pascals.
107000 Nm−2
Advertisements
उत्तर
1 Nm–2 = 1 Pa
∴ 107000 Nm–2 = 107000 Pa
= 1.07 × 105 Pa
107000 Nm−2 = 1.07 × 105 Pa

Solve the following.
A balloon is inflated with helium gas at room temperature of 25°C and at 1 bar pressure when its initial volume is 2.27L and allowed to rise in the air. As it rises in the air external pressure decreases and the volume of the gas increases till finally, it bursts when external pressure is 0.3bar. What is the limit at which the volume of the balloon can stay inflated?
Solve the following.
The volume of a given mass of a gas at 0°C is 2 dm3. Calculate the new volume of the gas at constant pressure when the temperature is increased by 10°C.
