• Multiple Choice questions on General Chemistry

  a. average density b. volume c. pressure d. molecular mass e. average kinetic energy Answer: e. average kinetic energy Kinetic Energy= 3/2 k T Where k= Boltzmann's constant T= temperature The van der Waals equation for real gases

• The hydrologic cycle in detail

  Water strikes the ground often loosening soil particles by transfer of kinetic energy, and some small generation of waste heat (or the ocean ... where minor heat energy is also created by the splash).

• Understanding Work, Energy & Power

  A part of the mechanical energy is wasted due to conversion to some other form such as heat. 6. Power: Two persons are doing same physical activity say bicycling. One takes lesser time to cover a given distance.

• Properties of Temperature, Heat and Their Relationship

  So, for instance, if you pour boiling water over ice, some energy will be transferred from the boiling water to the ice.

• Energy and the Laws of Thermodynamics

  For example, a tank of gasoline has a certain potential energy that is converted into kinetic energy by the engine. When the potential is used up, you're outta gas! Batteries, when new or recharged, have a certain potential.

• Energy of the Molecules of an Ideal Gas

  For example, when we expand gas, but keep heat from flowing in by insulating the container, the total change in the gas internal energy is negative. Thus its temperature drops (this is why air conditioners can cool).

• Basic thermodynamics of a resistor.

  The energy transferred from the resistor to the water is heat. The heat in the resistor is due to the electrons bouncing against each other and slowing down, losing kinetic energy.

• Quasistatic isothermal expansion and free expansion

  So, in the beginning the energy that you could use to extract work goes into the kinetic energy of the gas. The gas then collides with the walls of its new enclosure.

• Angular velocity, Final temperature

  If you want you can assume a 1 kg mass and obtain the kinetic energy that will be converted into heat. Multiply the specific heat of iron by one kg and divide that into this energy to obtain the change in temperature in C.

• Latent heat and energy during a phase transition

  The transition from ice to water and water to steam required energy. This example beautifully explains this process.
