When $0.93\,watt-hour$ of energy is supplied to a block of ice weighing $10\,g,$ it is found that
half of the block melts
entire block just melts
entire block melts and water reaches $4\,^oC$
block remain unchanged
The temperature of equal masses of three different liquids $A, B$ and $C$ are $12°C, 19°C$ and $28°C$ respectively. The temperature when $A$ and $B$ are mixed is $16°C$ and when $B$ and $C$ are mixed is $23°C$. The temperature when $A$ and $C$ are mixed is........ $^oC$
Two identical blocks of metal are at $20^{\circ} C$ and $80^{\circ} C$, respectively. The specific heat of the material of the two blocks increases with temperature. Which of the following is true about the final temperature $T_f$ when the two blocks are brought into contact (assuming that no heat is lost to the surroundings)?
We have half a bucket $(6l)$ of water at $20\,^oC$ . If we want water at $40\,^oC$, how much steam at $100\,^oC$ should be added to it ?
Boiling water is changing into steam. Under this condition, the specific heat of water is
$1\,\, kg$ of ice at $-10^o C$ is mixed with $4.4\,\, kg$ of water at $30^o C$. The final temperature of mixture is ........$^oC$ (specific heat of ice is $2100\,\,J/kg/k$)
