		It went down
		It went up
		It stayed the same
		It changed to Farenheit

Answer 1

When we pumped the particles in to the box , and decreasing the volume then the number of particles per unit volume increases there by the pressure on the walls of the box increases due to force per unit area by the particle , same time if there is any loss of energy per each collision by the particle with walls of the box , By conservation of energy , the total energy of the system remains constant, turns in to heat energy thereby Temperature also increases.

From ideal gas equation PV = nRT

As the volume decreases the pressure increases, provided the other parameters constant (Boyle's Law)

and the volume decreases the temperature remains constant, if the pressure and number particles are also constant
