Thermal Physics
In this post all the possible objective questions in the lesson Thermal Physics is given. By reading this post everyone must score atleast one mark in TNPSC Group2 TNPSC Group4 Exam. To prepare well for the TNPSC Group exams we need to study the samacheer text books.
_____ is the primary source of thermal energy for all living organisms.
Thermal energy is the cause and ______ is the effect.
All living organisms need a particular _____ for their survival
Temperature is the property, which determines the direction of flow of ____
The SI unit of temperature is _____
The temperature measured in relation to absolute zero using the kelvin scale is known as____
A temperature difference of 1°C is equal to that of ___
____Kelvin is the absolute scale of temperature of the body
____ always flows from one body to the other due to temperature difference between them.
Two or more physical systems or bodies are ____said to be in if there is no
net flow of thermal energy between the systems.
There will be a transfer of heat energy from the hot body to the cold body until a _____ is established between them.
When a hot object is in contact with another cold object, a form of energy flows from the hot object to the cold object, which is known as ____
____”‘ is also known as ‘heat energy’ or simply ‘heat’.
The SI unit of heat energy absorbed or evolved is ____
The ___ of a system is not altered when it is heated or cooled
_______is defined as the amount of heat energy required to rise the temperature of 1 gram of water through 1°C.
_____ is defined as the amount of heat energy required to risethe
temperature of 1 kilogram of water through 1°C.

When a solid is heated, the atoms gain energy and vibrate more vigorously. This results in the _____ of the solid
The extent of expansion is smaller in _____ than in liquids and gases
When a body is heated or cooled, the length of the body changes due to change in its temperature. Then the expansion is said to
be ____
The ratio of increase in length of the body per degree rise in temperature to its unit length is called as the______
The SI unit of Coefficient of Linear expansion is _____
If there is an increase in the area of a solid object due to heating, then the expansion is called _____

The ratio of increase in volume of the body per degree rise in temperature to its unit volume is called as _____
If a liquid is heated directly without using any container, then the expansion that you observe is termed as ____ of the liquid.
The expansion of a liquid apparently observed without considering the expansion of the container is called the ____ of the liquid.
The SI unit of coefficient of apparent expansion is_____
Charles’s law was formulated by a French scientist ____
If the atoms or molecules of a gas do not interact with each other, then the gas is said to be an ____
The above study material is made up by reading each and every line in the text book. These are all the possible objective questions in the lesson Thermal Physics. This is very useful when preparing for the TNPSC Group 2 and TNPSC Group 4 exams.
