If 10 cal of energy are added to 2 g of ice at -30°C calculate the final temperature of the ice

The final temperature of the ice is .

Explanation:

It is given that,

Energy, Q = 10 cal

Mass of ice, m = 2 g

Initial temperature,

We need to find the final temperature of the ice. We know that the specific heat of ice is

The heat added in terms of specific heat is given by :

final temperature of the ice

c is specific heat of ice

So, the final temperature of the ice is .

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
