Which one is greater CP or CV?

Which one is greater CP or CV?

cp is greater than CV because when gas is heated at constant volume,whole of the heat supplied is used to increase the temperature only. But when gas is heated at constant pressure,the heat supplied is used to increase both temperature and volume of gas.

How do you find pressure and volume on a graph?

We can find the work done by determining the total area under the curve on a PV diagram. We have to make sure we use the total area, all the way down to the volume axis. For instance, we can imagine viewing the area under the curve in the example shown above as a triangle and a rectangle (as seen below).

What is CP Delta T?

delta h = cp * delta T. where delta T is the change of temperature of the gas during the process,and c is the specific heat capacity. We have added a subscript “p” to the specific heat capacity to remind us that this value only applies to a constant pressure process.

What is the meaning of negative specific heat?

In a very simple words, negative specific heat means the increase in temperature when the system loses energy. In a very simple words, negative specific heat means the increase in temperature when the system loses energy.

What is the difference between specific heat and heat capacity?

Heat capacity is the ratio of the amount of heat energy transferred to an object to the resulting increase in its temperature. Specific heat capacity is a measure of the amount of heat necessary to raise the temperature of one gram of a pure substance by one degree K.

Why is my specific heat capacity negative?

Negative heat capacity would mean that when a system loses energy, its temperature increases.

Is specific heat capacity the same for all liquids?

The specific heat capacity often varies with temperature, and is different for each state of matter. Liquid water has one of the highest specific heat capacities among common substances, about 4184 J⋅kg−1⋅K−1 at 20 °C; but that of ice just below 0 °C is only 2093 J⋅kg−1⋅K−1.
