List of top Physics Questions on Calorimetry

The temperature of water of mass 100 g is raised from 24°C to 90°C by adding steam to it. The mass of the steam added is (Latent heat of steam = 540 cal/g and specific heat capacity of water = 1 cal/g°C)
40 g of water at 40°C is added to 10 g of water at 80°C. The final temperature of the mixture is 40°C

Under the same load, wire A having length $50 m$ and cross section $25 \times 10^{-5} m ^2$ stretches uniformly by the same amount as another wire $B$ of length $60 m$ and a cross section of $30 \times 10^{-5}$ $m ^2$ stretches The ratio of the Young's modulus of wire $A$ to that of wire $B$ will be :

A block of ice of mass $120\, g$ at temperature $0^{\circ} C$ is put in $300\, gm$ of water at $25^{\circ} C$ The $xg$ of ice melts as the temperature of the water reaches $0^{\circ} C$ The value of $x$ is [Use: Specific heat capacity of water $=4200\,Jkg ^{-1} K ^{-1}$, Latent heat of ice = 3.5 \(\times\) 105 JKg-1]

The water equivalent of a calorimeter is $10\, g$ and it contains $50 \,g$ of water at $15�C$. Some amount of ice, initially at $-10�C$ is dropped in it and half of the ice melts till equilibrium is reached. What was the initial amount of ice that was dropped (when specific heat of ice $= 0.5 \,cal\, gm^{-1}�C^{-1},$ specific heat of water $= 1.0 \,cal\, gm^{-1}�C^{-1}$ and latent heat of melting of ice $= 80 \,cal \,gm^{-1}$) ?
One kilogram of ice at $0^{\circ} C$ is mixed with one kilogram of water at $80^{\circ} C$. The final temperature of the mixture is (Take specific heat of water $=4200\, kJ / kg -{ }^{\circ} C$, Latent heat of ice $=336\, kJ / kg$ )
Calorie is defined as the amount of heat required to raise the temperature of $1 \,g$ of water by $1^{\circ} C$ and it is defined under which of the following conditions?
Three rods made of the same material and having the same cross-section have been joined as shown in the figure. Each rod is of the same length. The left and right ends are kept at 0$^{\circ}$C and 90$^{\circ}$C respectively. The temperature of junction of the three rods will be
Hot water kept in a beaker placed in a room cools from $ 70{}^\circ C $ to $ 60{}^\circ C $ in 4 minutes. The time taken by it to cool from $ 69{}^\circ C $ to $ ~59{}^\circ C $ will be:
Mercury thermometer can be used to measure temperature upto
The critical temperature of the gas is the temperature
