Mass of ice is 0.015 kg and that of water is 0.05 kg. Both are at 0°C. Find the final mass of ice and water.
MASS IS CONSERVED!
Until you get to Einstein and Special relativity, the total mass is CONSTANT.
.015 + .050 = .065 kg
To find the final mass of ice and water, we need to consider the process of phase change and the principle of conservation of mass.
When ice at 0°C is heated, it undergoes a phase change and melts into water at 0°C. During this process, no mass is lost or gained. So, the total mass of ice and water remains constant.
Given:
Mass of ice (m₁) = 0.015 kg
Mass of water (m₂) = 0.05 kg
To find the final mass, we simply add the masses of ice and water:
Final mass = m₁ + m₂
Final mass = 0.015 kg + 0.05 kg
Final mass = 0.065 kg
Therefore, the final mass of ice and water is 0.065 kg.
