What is heat? What is energy?

Expert Solution

Heat is a form of Energy

Energy is necessary one for a object to do work

Energy can't be created or destroyed but energy can be converted in to one form to another form

The forms of energy are

Heat energy

Electrical Energy

Mechanical Energy

Chemical energy

Electro megnetic wave energy

Unit of Energy is Jule and it's sympol is J

1 Jule = 1 kg m^2/s^2

1 Jule = 6.24 × 10^18 eV

1Jule = 1×10^7 erg

1 Jule = 2.39 × 10^-4 kcal

1 Jule = 2.78 ×10^-7 kW.h

1Jule = 1 N.m

Heat and work are inter convertable

There is a heat , work will be done

There is a work , heat will be generated

All heat engines are converting heat into work

Chemical reactions which taking place spontaneously are releasing heat energy , thus lead to the work and this is the basic concept for electro chemical cell.

if you transfer heat energy to a perfectly insulated cup of some liquid (no heat energy can be transferred in or out through the walls) what determines how much the temperature changes? Does it depend on how much heat energy you transfer, how much liquid there is in the cup, what the liquid is, or what the initial temerpature of the liquid is? Which of these factors do you think make a differnce in how much the temperture rises?

Heat Transfer Mechanisms What are the four mechanisms of heat/energy transfer? Give an example for each. What happens to energy when water evaporates – gained or lost? What happens to energy when water condenses –gained or lost? Explain how thermohaline circulation of ocean water affects global temperature distribution. Must be 350 words long. give a good explanation and examples of each. this is physical geography. they have to be long explanation.

Heat of Vaporization and Heat of Fusion Learning Goal: To calculate the total energy required to convert a solid to a gas using heat capacity, heat of fusion, and heat of vaporization. The amount of heat required to melt one mole of a solid is called the heat of fusion (ΔHfus). The amount of heat required to vaporize (boil) one mole of a liquid is called the heat of vaporization (ΔHvap). The heat of fusion and the heat of vaporization...

A heat engine receives an amount of energy Qh= 790 kJ by heat transfer from a high temperature thermal reservoir at Th=950 K. Energy is rejected by heat transfer to a lower temperature thermal reservoir at T1=590 K. If waste heat in the amount of Q1=160 kJ is rejected to the low temperature thermal reservoir during each cycle. a) Solve for the maximum theoretical efficiency that an engine in this situation could operate with. ANSWER: 0.379 b) Solve for actual...
