Answer:

height(h)=10 m

acceleration due to gravity (g)=10 m/s^2

mass (m)=?

potential energy=67

or,mgh= 67

or,m×10×10=67

or,m=67/100

or,m=0.67 kg

Therefore,m= 670 grams

How does a substances temperature change when the average kinetic energy of its particles increases ? When the average kinetic e
Novay_Z [31]

Answer:

The temperature of a substance when the average kinetic energy of its particles increases and decreases when the average kinetic energy decreases.

Explanation:

Atoms and molecules are in constant motion. Kinetic energy is a form of energy, known as energy of motion. Kinetic energy is a form of energy, known as energy of motion. The kinetic energy of an object is that which is produced due to its movements, which depends on its mass (m) and speed (v).

Temperature refers to a quantity used to measure the kinetic energy of a system. That is, temperature is defined as an indicator of the average kinetic energy of the particles in a body.

So, since temperature is a measure of the speed with which they move, the higher the temperature the faster they move.

Finally, <u><em>the temperature of a substance when the average kinetic energy of its particles increases and decreases when the average kinetic energy decreases.</em></u>
