Question

If $10$g of ice at $0^{o}C$ is mixed with $10g$ of water at ${40}^{o}C$, the mixture is

• A. $10$g
• B. $15$g
• C. $18$g
• D. $20$g

Answer 1

The correct option is A $10$g

If $m=10g$ of ice

$t=0°C$

Mixed with $m_1=10g$ of water

$t=40°C$

The mixture will be same amount.

According to law of conservation energy

The mass of water, either solid or liquid is not a function of temperature.
