Chapter 8: Problem 1117

The first law of thermodynamics is concerned with the conservation of (A) momentum (B) energy (C) mass (D) temperature

Short Answer

Expert verified
The correct answer is (B) energy, as the first law of thermodynamics is concerned with the conservation of energy and states that energy cannot be created or destroyed, only converted from one form to another.

Step by step solution

01

Choose the correct answer based on the conservation concept

Comparing all the given options, we can see that: (A) momentum: This is not related to the conservation of energy. (B) energy: This is the correct answer, as the first law is about the conservation of energy. (C) mass: This is not applicable as the conservation of mass is not the focus of the first law of thermodynamics. (D) temperature: This is also incorrect as the first law of thermodynamics is not about the conservation of temperature. So, based on the given options, we find that the correct answer is (B) energy, which represents the conservation concept in the first law of thermodynamics.

The Specific heat of a gas in an isothermal Process is (A) zero (B) Negative (C) Infinite (D) Remairs

A monoatomic ideal gas, intially at temperature \(1_{1}\) is enclosed in a cylinders fitted with a frictionless piston. The gas is allowed to expand adiabatically to a temperature \(\mathrm{T}_{2}\) by releasing the piston suddenly If \(\mathrm{L}_{1}\) and \(\mathrm{L}_{2}\) the lengths of the gas column before and after expansion respectively, then then \(\left(\mathrm{T}_{1} / \mathrm{T}_{2}\right)\) is given by (A) \(\left\\{\mathrm{L}_{1} / \mathrm{L}_{2}\right\\}^{(2 / 3)}\) (B) \(\left\\{\mathrm{L}_{2} / \mathrm{L}_{1}\right\\}^{(2 / 3)}\) (C) \(\left\\{\mathrm{L}_{1} / \mathrm{L}_{2}\right\\}\) (D) \(\left\\{\mathrm{L}_{2} / \mathrm{L}_{1}\right\\}\)

If \(r\) denotes the ratio of adiabatic of two specific heats of a gas. Then what is the ratio of slope of an adiabatic and isothermal $\mathrm{P} \rightarrow \mathrm{V}$ curves at their point of intersection ? (A) \((1 / \gamma)\) (B) \(\gamma-1\) (C) \(\gamma\) (D) \(\gamma+1\)

For hydrogen gas \(\mathrm{C}_{\mathrm{p}}-\mathrm{C}_{\mathrm{v}}=\mathrm{a}\) and for oxygen gas \(\mathrm{C}_{\mathrm{p}}-\mathrm{C}_{\mathrm{v}}=\mathrm{b}\), The relation between \(\mathrm{a}\) and \(\mathrm{b}\) is given by (A) \(a=4 b\) (B) \(a=b\) (C) \(\mathrm{a}=16 \mathrm{~b}\) (D) \(a=8 b\)

For adiabatic Process which relation is true mentioned below ? \(\gamma=\left\\{\mathrm{C}_{\mathrm{p}} / \mathrm{C}_{\mathrm{v}}\right\\}\) (A) \(\mathrm{p}^{\gamma} \mathrm{V}=\mathrm{Const}\) (B) \(\mathrm{T}^{\gamma} \mathrm{V}=\mathrm{Const}\) (C) TV \(^{\gamma}=\) Const (D) \(\mathrm{TV}^{\gamma-1}=\) Const
