refer to a cup which contains water at room temperature. The cup is perfectly insulated so that no heal can transfer into or out of the cup. A small coffee cup heater inside the cup is used to transfer heat to the water. The water does not boil. If heat is transferred to the cup at a steady rate, which of the graphs below best represents the shape of the graph...

A sample of carbon monoxide gas is heated at constant pressure until its temperature increases by 62.3 degree C. A sample of neon gas is heated at constant volume until its temperature increases by 22 degree C. If each sample of gas absorbs the same amount of heat, what is the ratio of the number of moles of neon to the number of moles of carbon monoxide?

Calculating specific heat capacity A constant-pressure calorimeter is often used to find the specific heat capacity of a substance if it is not known. A known mass of the substance can be heated and added to water of known mass and initial temperature. Since the specific heat capacity of water is known ( C s,water =4.184J/(g⋅ ∘ C)) , the amount of heat transferred to the water can be calculated by measuring the final temperature of the mixture at thermal...

A 48.79 g sample of metal is heated to 98.77oC and then quickly transferred to 88.34 mL of water at 24.65oC contained in a new calorimeter. This calorimeter has a calorimeter constant (heat capacity) with a numerical value of 55.7 (see problem 2e above for appropriate units). The thermal equilibrium temperature of the metal sample plus water mixture was 27.49oC. Assume the density of the water is 1.00 g/mL. a. How much heat in Joules is gained by the water?...

a 312 g sample of a metal is heated to 355.272 c
A 312 g sample of a metal is heated to 355.272 °C and plunged into 200 g of water at a temperature of 45.471 °C. The final temperature of the water is 59.19 °C. Assuming water has a specific heat capacity of 4.184 J/g °C, what is the specific heat capacity of the metal sample, in J/g °C)? Assume no heat loss to the surroundings. Report your response...

A 61.18 gram sample of iron (with a heat capacity of 0.450 J/g℃) is heated to 100.00。It is then transferred to a coffee cup calorimeter containing 52.33 g of water (specific heat of 4.184 J/ g℃) initially at 20.67 ℃. If the final temperature of the system is 28.40, what was the heat gained by the calorimeter? If the calorimeter had a mass of 27.88 g, what is the heat capacity of the calorimeter? J absorbed by the calorimeter
