While attempting to forge a sword in Skyrim, you obtain an iron ore sample of unknown mass to work with. The iron ore sample has a resting temperature of 4°C. In order to reach the forging temperature of the iron, 974°C, the system requires 225 calories, which is supplied by the forge. Given that the specific heat of the iron ore sample is 0.111 kcal/kg°C, what is the mass, m, of the iron ore sample in kg?

In 2011, artist Hans-Peter Feldmann covered the walls of a gallery at the New York Guggenheim Museum with 100,000 one-dollar bills (Fig. P1.48). Approximately how much would it cost you to wallpaper your room in one-dollar bills, assuming the bills do not overlap? Consider the cost of the bills alone, not other supplies or labor costs.

A picture window has dimensions of 1.25 m by 2.6 m and is made of glass 7.5 mm thick. On a winter day, the outside temperature is 22° C while the inside temperature is a comfortable at 19° C. (k of glass =0.075W/m.K) Calculate the following:a) the area of the window in square metres
How much heat Q would be needed to completely evaporate 37.5 g of boiling water at a temperature of 100 °C? Express the answer in units of joules. The latent heat of vaporization for water at 100 °C is 2260 J/g. Q =
Eggs with a mass of 0.15kg per egg and a constant pressure specific heat of 3.32 kJ/kg-K are cooled from 32C to 10C at the rate of 300 eggs per minute. Compute the rate of heat removal from these eggs in kW. FYI: kW = kilowatt = kJ/s
How much heat is removed when 100 g of steam at 150◦C is cooled and frozen into 100g of ice at 0◦C. Note that the specific heat of ice is 2, 010 J / kg ·K and the specificheat of liquid water is 4, 186 J / kg ·K.
The specific heat of aluminum is 0.90 1/3-C. How much heat must be added to a 245-gram aluminum pot containing 556 grams of water to raise the temperature from 22.1°C to 97.4°C? What percentage of this heat is used to heat the aluminum pot? Hint: Apply the Law of Conservation of Energy. The heat required to warm up the pot with the water in it is the same amount of heat that would be required to warm up the put and the water separately. 2. For each of the following experimental errors clearly state if the error would increase, decrease, or have no effect on the specific heat that you determined in today's experiment. You must explain your reasoning
Luis and Salman are trying to increase the temperature of a substance by heating it.. What is the quantity of heat in kilojoules required to raise the temperature of 3.2 kg of the substance from1° C to 115 °C at a pressure of 1.0 atm? Please keep three significant figures. Useful information: Melting point = 293 K heat of fusion =3.90 x 104 J/kg. boiling point is 423 K heat of vaporization 7.80 x 104 J/kg (at a pressure of 1.0 atm). The specific heats for the solid phase is 600 J/(kg K) The specific heats for the liquid phase is 1000 J/(kg K) The specific heats for the gaseous phase is 400 J/(kg K) 339.2 20 F3 4 900 F4 % 5 F5 A 6 tv Ni MacBook Air F6 7 F7 * F8 A 9
A metal bar in a low temperature physics experiment with mass m = 89 kg had its temperature raised from T1 = 26 K to T2 = 46 K. The metal bar has a specific heat that is a function of temperature:c(T) = A + αT, where A = 380 J/(kg⋅K) and α = 9.9 J/(kg⋅K2). Note the metal bar does not change in volume as it is heated. Calculate the amount of heat Q in joules required to raise the temperature on the metal bar as stated. Calculate heat released by the metal bar when cooling from T2 to T1 without any change in volume. Write an approximation of the c(T) for the metal rod for very high temperatures (say T >> 1000 K).
