Water at 22.0 °C is sprayed onto 0.136 kg of molten gold at 1063 °C (its melting point). The water boils away, forming steam at 100.0 °C and leaving solid gold at 1063 °C. What is the minimum mass of water that must be used?

You happen to come across a piece of metal that has a density of p 8.12 g/cm3 when the temperature is To = 42.5 °C. If the metal is cooled to a temperature of T1 0.00 °C, does the density change? Yes, the density will decrease since the volume changes. Yes, since the metal contracts and the mass is constant, the density will increase. No, because as the volume changes so does the mass. No, density does not depend on temperature. Calculate the density of the piece of metal at this temperature, P1. The coefficient of volume expansion for this piece of metal is B = 7.62 x 10-5 1/°C. -0.0263 Pi = g/cm3 Incorrect

Water at 16.0 °C is sprayed onto 0.230 kg of molten gold at 1063 °C (its melting point). The water boils away, forming steam at 100.0 °C and leaving solid gold at 1063 °C. What is the minimum mass of water that must be used? mw =

The temperature of a 5.00-kg lead brick is increased by 525 C°. If the specific heat capacity of lead is 128 J/(kg.C°), what is the increase in the mass of the lead brick when it has reached its final temperature? O 5.80 × 10- -11 kg O 9.12 × 10-11 kg O 1.60 × 10-12 kg O 3.73 × 10-12 kg O 2.80 × 10-12 kg

A 0.290 kg aluminum bowl holding 0.815 kg of soup at 25.0°C is placed in a freezer. What is the final temperature (in °C) if 391 kJ of energy is transferred from the bowl and soup, assuming the soup's thermal properties are the same as that of water?     °C

A metal rod has a starting length of 240 cm. When the temperature changes from 25 °C to 110 °C, the length of the rod changes 0.115 cm. What is the linear expansion coefficient of the rod?

Water is placed into an iron container along with an ice cube. They are thermally isolated.The iron container has a mass of 790. g and is initially at 72.0 degrees Celsius. The water has a mass of 220. g and is initially at 17.0 degrees Celsius. The ice cube has a mass of 80.0 g and is initially at -15.0 degrees Celsius.What is the heat required to raise the temperature of the ice to 0 degrees Celsius?

A hot air balloon uses the principle of buoyancy to create lift. By making the air inside the balloon less dense then the surrounding air, the balloon is able to lift objects many times its own weight. A large hot air balloon has a maximum balloon volume of 2090 m3. a.  If the air temperature in the balloon is 54 °C, how much additional mass, in kilograms, can the balloon lift? Assume the molar mass of air is 28.97 g/mol, the air density is 1.20 kg/m3, and the air pressure is 1 atm.

A thermos contains 160 cm3 of coffee at 93.2 °C. To cool the coffee, you drop two 10.5-g ice cubes into the thermos. The ice cubes are initially at 0 °C and melt completely. What is the final temperature of the coffee in degrees Celsius? Treat the coffee as if it were water.
