A 15-g sample of the candy is placed in a small aluminum container of mass 0.325 kg filled with oxygen. This container is placed in 1.75 kg of water in an aluminum calorimeter cup of mass 0.624 kg at an initial temperature of 15.0 ∘C. The oxygen-candy mixture in the small container (a "bomb calorimeter") is ignited, and the final temperature of the whole system is 53.5 ∘C.The value of specific heat for aluminum is 0.22 Cal/kg⋅C∘, and for water...

Mass of the calorimeter cup = 60 gm; mass of water= 100 gm; water equivalent mass of coil =2.5 gm; initial temperature of the water = 20° C; final temperature of water in cup = 41° C; total heating time = 20 minutes. Using this initial data set, complete the rest of the data sheet. Take the specific heat of the water as 1cal/gmº C and cup as 0.22 cal/gmº C. The average current and voltages are 2.75 A and...

In an insulated container of negligible mass, 900 g of water at 25.0oC is mixed with 765 g of ice at -18.0oC. After several minutes, it is observed that only part of the ice has melted and that the remaining ice is in thermal equilibrium with the surrounding water. What is the temperature of the unmelted ice? Calculate the heat lost by the 900g of water. Calculate the mass of ice that is melted in this process. The specific heat...

Scientists are conducting an experiment with a gas in a sealed container. The mass of the gas is measured, and the scientists realize that the gas is leaking over time in a linear way. Its mass is leaking by 8.6 grams per minute. Five minutes since the experiment started, the remaining gas had a mass of 369.8 grams. Let x be the number of minutes that have passed since the experiment started, and let y be the mass of the...

Suppose an oven’s radiation wavelength is 0.125 m. A container with 350.00 g of water was placed in the oven, and the temperature of the water rose from 20.0°C to 80.0°C. How many photons of this microwave radiation were required to heat the water? (Assume that all the energy from the radiation was used to raise the temperature of the water.)
