Heat

The average kinetic energy of the molecules of a body determines

• Heat

• Internal energy

• temperature

• none

273 K is equal to

• 32F

• 0F

• 20F

• 10F

Two ends "A" and "B" of a rod are temperature -10C and -30C , the heat will flow from

• -30 to -10 C

• -30 to -50 C

• -10 to -30 C

• -10 to -20 C

The volume of a given gas at constant pressure becomes zero at :

• 273K

• 200K

• 300K

• -273K

A bimetallic thermostat works on the principle of :

• Linear expansion

• bulk expansion

• volumetric expansion

• all of these

According to Second Law of thermodynamics 100 percent of conversion heat energy into work is :

• possible

• not possible

• possible with condition

• Sometimes possible

If no heat flows into or out of the system ,the process is called :

• Adiabatic

• Isochroic

• Isothermal

• Isobaric

In adiabatic expansion , The internal energy of the gas :

• Remains same

• decreases

• increases

• becomes zero

The SI unit of Heat energy is

• Calorie

• Joule

• BTU

• None

The unit of coefficient of linear and volumetric conversion is

• K

• K^-1

• K^-2

• K²
