Though Babatunde's family take oats for breakfast, her mum decides that today they wouldtake tea. She prepares it and serves Babatunde in an aluminium cup of mass 120 g. Beforeserving the tea, the cup had a temperature of 20 °C. The 0.30 kg tea that is poured into the cupis at a temperature of 70 °C. Determine the final temperature when thermal equilibrium isattained between the tea and the cup, assuming no exchange of heut with the surrounding?

A 6.25 kg block ice at 0 degrees Celsius is being warmed on a glass stove top. The thermal conductivity of the glass is 1.00 W/ (m K) and the glass is 0.50 cm thick. If the radiator plate underneath the glass raises the temperature of the bottom of the glass to 125 degrees Celsius, how long would it take to completely melt the ice? Assume the ice remains a solid rectangle with a square base of side 15 cm as it melts. B. What is the rate of entropy change in Joules/ Kelvin/ seconds of the melting ice?
In an experiment measuring the latent heat of fusion of water, the following procedure was followed. Ice cube of mass 35.0 g at an initial temperature of 0.0°C is dropped into 225.0 g of 65.0°C water in an aluminum container. The mass of the aluminum container is 44 .0 g and the final equilibrium temperature is 46.0℃. Determine whether any heat is lost or gained in this experiment to the environment. If yes, how much? (For water: c = 1.00 cal/g×°C and Lf = 77.9 cal/g; for Al: c = 0.215 cal/g×°C
An aluminum cup with mass 0.34 kg holds 0.36 kg of water. Both the cup and the water have a temperature of 12.°C. If a 0.13-kg piece of copper at 62.°C is added to the cup, what is the final equilibrium temperature in °C? You may assume that the cup, water, and copper are well insulated from anything else.
A 0.065-kg ice cube at -30.0°C is placed in 0.375 kg of 35.0°C water in a very well-insulated container. The latent heat of fusion for water is Lf = 79.8 kcal/kg Chart attached. What is the final temperature of the water, in degrees Celsius?
8.33 A 2 kg block is moving at a speed of 10 m/s and makes a perfectly elastic collision with a second block of mass MM, which is initially at rest. After the collision, the 2 kg block bounces straight back at 3 m/s. Determine the mass M of the second block. Express your answer with the appropriate units. Determine the speed of the second block after the collision. Express your answer with the appropriate units.
