What happens when gas expands at constant pressure?
Therefore, when gas expands at a constant temperature,
pressure decreases as well
as kinetic energy of the molecules will remain the same.
When an ideal monoatomic gas is heated at constant pressure percentage of heat energy?
When an ideal monoatomic gas is heated at constant pressure, fraction of heat energy supplied which increases the internal energy of gas, is. i.e., fraction of heat energy to increase the internal energy be
3/5
.
Which is constant in isothermal process?
An isothermal process is a change of a system, in which the temperature remains constant:
ΔT = 0
. … In contrast, an adiabatic process is where a system exchanges no heat with its surroundings (Q = 0).
When an ideal diatomic gas is heated at?
An ideal diatomic gas is heated at
constant pressure
.
What happens when one mole of gas is heated at constant volume?
When 1 mole of gas is heated at constant volume, the temperature is raised from 298 to 308 K and heat supplied to gas is
500 J
.
Why the specific heat at a constant pressure is more than that at constant volume?
The heat capacity at constant pressure CP is greater than the heat capacity at constant volume CV , because
when heat is added at constant pressure, the substance expands and work
. QV = CV △T = △U + W = △U because no work is done. Therefore, dU = CV dT and CV = dU dT .
When a monoatomic gas expands at constant pressure the percentage of heat supplied that increase the internal energy of the gas and that which is involved in expansion is?
The percentage of heat supplied that increases the internal energy of the gas and that is involed in the expansion is. Therefore, percentage
energy =30/5=60%
.
What happens if gas expands at constant temperature?
Coming to option C,
Kinetic energy of molecules remains the same
. It is correct because at constant temperature kinetic energy of the gas remains the same. Therefore, if gas expands at a constant temperature the kinetic energy of the molecules remains the same.
When a gas is compressed at constant temperature What is it called?
Hence, when the gas is compressed,
its molecules come closer and internal energy of gas is increased and the number of collisions will also increase
. As the gas is compressed, the work done on it shows up as increased internal energy, which must be transferred to the surroundings to keep the temperature constant.
Is it possible to decrease the temperature of a gas without removing any heat from the gas?
No, there is no way to decrease the temperature
of a gas without removing heat from it. Yes, if the gas is allowed to expand in an adiabatic process the pressure decrease and volume increase provide the work of the system.
Can molar heat capacity of a gas be negative?
To answer in simple words, Yes. The molar specific heat capacity
can be negative
. It can be negative when we consider a polytropic process and the value of n in the range 1 < n < γ.
When the gas is heated at constant pressure the heat supply?
Therefore, the heat supplied
increases the internal energy of the
gas and increases the temperature of the gas.
