Description
A thermally insulating cylinder has a thermally insulating and frictionless movable partition in the middle, as shown in the figure below. On each side of the partition, there is one mole of an ideal gas, with specific heat at constant volume, C
V
=2R. Here, R is the gas constant. Initially, each side has a volume V
0
and temperature T
0
. The left side has an electric heater, which is turned on at very low power to transfer heat Q to the gas on the left side. As a result the partition moves slowly towards the right reducing the right side volume to V
0
/2. Consequently, the gas temperatures on the left and the right sides become T
L
and T
R
, respectively. Ignore the changes in the temperatures of the cylinder, heater and the partition.
Frequently Asked Questions
How to prepare for IIT-JEE Physics?
To prepare for IIT-JEE Physics, focus on understanding concepts rather than memorizing formulas. Practice solving a variety of problems, especially previous years’ questions. Create a study schedule that covers all topics, with extra time for challenging areas like Mechanics and Electromagnetism. Regular revision and mock tests are essential for success.
What is the difference between elastic and inelastic collisions?
In elastic collisions, both momentum and kinetic energy are conserved. Examples include collisions between hard billiard balls. In inelastic collisions, only momentum is conserved while some kinetic energy is converted to other forms like heat or sound. Most real-world collisions are inelastic to some degree.
What is the difference between heat and temperature?
Heat is the total energy of molecular motion in a substance, measured in joules (J) or calories. Temperature is a measure of the average kinetic energy of molecules in a substance, measured in degrees Celsius (°C) or Kelvin (K). Heat flows from objects at higher temperatures to objects at lower temperatures.
