Question

Answer the questions atleast 5 questions​

Answer 1

Answer:

1-Heat can flow in a vacuum by a process called radiation, which is the transfer of energy through electromagnetic waves. Heat flows in solids by conduction, which occurs when two objects in contact with each other transfer heat between them.

2-The state of a thermal equilibrium denotes a state of body where it neither receives nor gives out heat energy.

3-Basis for CGS is centimetre, gram, second. Temperature and time have same units in both CGS and MKS systems. In both SI and CGS system, Kelvin is used to measure the temperature

Answer 2

1) Heat can flow in a vacuum by a process called radiation, which is the transfer of energy through electromagnetic waves. Heat flows in solids by conduction.

2) Thermal state of the body where it neither receives nor gives out heat energy.

3) Kelvin (K) is the SI and CGS unit to measure temperature.

5) The average kinetic energy of molecules is hotter body is greater than that of the colder body.

8) The density of seawater is about 1025 kg/m^3 and the specific heat is about 3850 J/(kg C).
