Heat, Internal Energy and Work

When work done by a system was $10 \mathrm{J}$, the increase in the internal energy of the system was $30 \mathrm{J}$. The heat 'q' supplied to the system was

Consider the following statements-

a) $q$ is a state function in isochoric process.

b) $w$ is state function in isobaric process.

c) Work done by the system will be zero in adiabatic free expansion.

Correct among the following is/are

The net work done by an ideal gas going through the cycle as shown in the $P-V$ diagram below is

The internal energy of an ideal gas depends on

A gas mixture consist of $3.0$ mole of hydrogen and $2.0$ mole of Helium at absolute temperature $T$. Considering all vibrational modes, (assume zero internal energy at $T=0$) the total internal energy of the system is

A monatomic gas (ideal) is supplied $80$ joule heat at constant pressure. The internal energy of gas, increases by

Is mass related to internal energy in thermodynamics?

Two moles of an ideal non-linear triatomic gas undergo a transition from $A$ to $B$ along a path $AB$ as shown in the figure. Change in internal energy of the gas is

Three moles of an ideal monatomic gas perform a cycle as shown in figure. The gas temperatures in different states are $T_1=400 \mathrm{K},T_2=800 \mathrm{K},T_3=2400 \mathrm{K},T_4=1200 \mathrm{K}$. Find the work done by the gas during the cycle in $\mathrm{kJ}$: (use $\mathrm{R}=\frac{25}{3}$)

A gas mixture consists of $2 \mathrm{mol}$ of oxygen and $4 \mathrm{mol}$ of argon at temperature $T$. Neglecting all vibrational modes, the total internal energy of the system is $xRT$. Find $x$.

One mole of a monoatomic gas is taken from $P$ to $R$, via three paths $PQR, PR$ and $PSR$. If work done by the gas in $PQR$ is $W_1$, in $PR$ work done is $W_2$ and in $PSR$ work done is $W_3$, then

Distinguish between internal energy and heat.

What is the difference between heat and internal energy?

Define work done in a thermodynamic process.

An ideal monoatomic gas is confined in a horizontal cylinder by a spring loading piston (as shown in Fig $20.63$). Initially the gas is at temperature $T_1$ pressure $P_1$ and volume $V_1$ and the spring is in relaxed state. The gas is then Fig. $20.63$ heated very slowly to temperature $T_2$, pressure $p_2$ and volume $V_2$. During this process the piston moves out by a distance $X$. Ignoring the friction between the piston and the cylinder, the correct statements $\left(s\right)$ is (are)

Which part of the solar cooker is responsible for the green house effect?

What is the distinction between heat and internal energy?

An ideal is filled in a closed, rigid and thermally-insulated container. A coil of $100\mathrm{\Omega }$ resistance and carrying a current of $1 \mathrm{A}$ supplies heaT to the gas. The change in the internal energy of the gas after $5$ minutes will be:

For an ideal gas, its internal energy is the function of its:
