A thermometer is check at the normal freezing point of tin (505.118k) and found to read 512.2k. At the normal freezing point of silver (1235.08k) it reads 1236.5k. Estimate the thermometer reading when the true temperature is 742.5k

If the initial temperature of the sample is 63.5°F, what is its temperature in degrees Fahrenheit when the desired temperature increase has been achieved (3 sig fig)

A ceramic heater element is 30.5 cm by 10.2 cm by 5 cm. It is rated at 1500 W and emissivity of .68. The surrounding area is at 20 0C. What is the temperature of the element?

What is the equilibrium temperature if a 0.560 kg piece of copper at 251 degC is placed in a 0.390 kg aluminum cup with 4.30 kg of water at the same initial temperature of 23.3 degC?

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.
