Answer 1

Answer:-

Q1:-What is the difference between heat and temperature?

Answer :-

Heat describes the transfer of thermal energy between molecules within a system and is measured in Joules. Heat measures how energy moves or flows. ... Temperature describes the average kinetic energy of molecules within a material or system and is measured in Celsius (°C), Kelvin(K), Fahrenheit (°F), or Rankine (R).

Q2:-What is a bimetallic strip? Give one use of it.

Answer:-

A bimetallic strip is used to convert a temperature change into mechanical displacement. The strip consists of two strips of different metals which expand at different rates as they are heated.

Q3:-3. At which temperature the value in Fahrenheit and Celsius scale will be equal? Explain.

Answer:-

There is one point on the Fahrenheit and Celsius scales where the temperatures in degrees are equal. This is -40 °C and -40 °F.

Q4:-4. Show an example where you can observe the flow of heat by all the 3 ways.

Answer:-There are three basic ways to transfer heat energy: convection, conduction, and radiation. Convection transfers heat energy through gases or liquids. Conduction transfers heat energy from one solid to another. Radiation transfers heat in the form of waves or particles through places where there are no molecules

Q5:-What are the two conditions necessary for conduction?

Answer:-

The condition required for conduction of heat is the temperature difference between the ends of material (rod or any other form). Also, for conduction between two bodies, the bodies need to be in contact, along with having a temperature difference of course.

Hope it helps you ✌️✌️
