1. A1 m' rigid tank has air at 100 kPa, 300 K and connected by a valve to another tank of 0.5 m3 with air at 250 kPa, 400 K. The valve is opened and the air in the two tanks mix until the mixture comes to a uniform state at 326 K. What is the final pressure of the mixture? (Select the closest value) [Whenever necessary, assume air as an ideal gas and consider R = 287 J/(kg.K).] 2.

Without any change in the volume, ignition occurs, and the air temperature rises to 1500°C. What is the air pressure after the ignition? (Select the closest value) [Whenever necessary, assume air as an ideal gas and consider R = 287 J/(kg.K).] 3. A 1-m tank is filled with air at room temperature 20°C and pressure 100 kPa. How much air is in the tank? (Select the closest value)

Question
1. A1 m' rigid tank has air at 100 kPa, 300 K and connected by a
valve to another tank of 0.5 m3 with air at 250 kPa, 400 K. The
valve is opened and the air in the two tanks mix until the mixture
comes to a uniform state at 326 K. What is the final pressure of the
mixture?
(Select the closest value)
[Whenever necessary, assume air as an ideal gas and consider R =
287 J/(kg.K).]
2. In the engine of a car that uses petrol as fuel, when the piston is at
its highest position, air at 10 bar and 100°C enters the cylinder.
Without any change in the volume, ignition occurs, and the air
temperature rises to 1500°C. What is the air pressure after the
ignition?
(Select the closest value)
[Whenever necessary, assume air as an ideal gas and consider R =
287 J/(kg.K).]
3. A 1-m' tank is filled with air at room temperature 20°C and
pressure 100 kPa. How much air is in the tank? (Select the closest
value)
[Whenever necessary, assume air as an ideal gas and consider R =
287 J/(kg.K).]
4. At constant temperature, the volume of a gas is inversely
proportional to its pressure.
[Whenever necessary, assume air as an ideal gas and consider R =
287 J/(kg.K).]
5. A laboratory room keeps a vacuum with absolute pressure of 0.2
kPa. What net force does that put on a door of size 2m by 1m?
[Whenever necessary, assume air as an ideal gas and consider R =
287 J/(kg.K).]
6. Which property is not an intensive property of a matter?
[Whenever necessary, assume air as an ideal gas and consider R =
287 J/(kg.K).]
