Question

The Following Questions are all either True or False 1. The exchange of energy between any two objects because of differences in their temperatures is known as heat. 2. As the temperature of a gas decreases, the molecules move with higher average kinetic energy. 3. The internal energy for a gas is inversely proportional to the absolute temperature of the the gas. 4. If an ice cube absorbs heat, then its temperature must always increase. 5. Conduction makes the metal handle of a cooking pan hot. 6. In order for a particle of mass m to exhibit simple harmonic motion, the magnitude of it's acceleration must be directly proportional to the square of the displacement from its equilibrium position. 7. The greater the displacement from equilibrium of an object is, the higher the frequency of its oscillation. 8. If the mass of the spring system is doubled, then the period of oscillation will also be doubled. 9. The period of a pendulum on earth decreases if the same pendulum oscillates on the surface of mars. 10. The speed of the mass in a spring-mass system is maximum at the greatest displacement. So for I have 1.T 2.F 3.F 4.T 5.F The others Im unsure on let me know if the previous five are correct as well.

Explanation / Answer

1. T : Very clear...as per definition 1. F : It decreses 3. F : 4. F : Latent heat will not increase temperature 5. T : Very true...Heat is directly transfered from pan to handle by conduction 6. T : Basic definition 7. F : Frequency doesnot depends upon amplitude...only on angular speed 8. F : It will one- fourth 9. F : It will increase...since g is less on mars... 10. F : It is least at that point
