A long-dried towel is placed on the heated radiator. Will they feel equally hot when touched? Will their temperature be the same? Why?
Homework Answers
Yes they will feel equally hot and they will have the same temperature. On coming in contact, heat will be transferred from the radiator to the towel. This will continue until they attain equilibrium, I.e same temperature. Thus they attain the same equilibrium temperature and feel equally hot.

. A 150.0 g sample of a Metal was heated to 95.0°C. When the hot metal was placed into 100.0 g of water in a calorimeter, the temperature of the water increased from 20.0°C to 35.0°C. The specific heat of water is 4.184 J/g °C. a) What is the specific heat of the metal? Kb) What would the final temperature be if the mass of water was 150.0 q?

Thermodynamics
A 29-L electrical radiator containing heating oil is placed in a 41-m3 room. Both the room and the oil in the radiator are initially at 10°C. The radiator, with a rating of 1.8 kW, is now turned on. At the same time, heat is lost from the room at an average rate of 0.35 kJ/s. After some time, the average temperature is measured to be 20°C for the air in the room, and 50°C for the oil in the...

3. You have been asked to investigate the feasibility of employing hot air (70 C) forced convection to produce a dried carrot stick snack food. Based on experiments, you have determined that the combined average overall heat transfer coefficient for a nominal "skinny" carrot (1.4 cm diameter, 14 cm long), when heated from 24 C in 70 C air, is 122 w/m2oK. Assume that the carrot density is 1079 kg/m3, with a specific heat of 3,790 J/kg"к, and thermal conductivity...

a long iron rod is heated to 700 degrees celcius. the rod is then placed in a water bath that is at a constant temperature of 50 degrees celcius with h= 128 W/m^2 * K. How long will it take the iron rod surface to cool to 200 degrees celcius? use the one term approximation method. for iron: p = 7870 kg/m^3, Cp=447 J/kg *K, k = 80.2 W/m * K. No diameter given

Choose the correct statement below regarding heat and temperature. When a hot object is placed in contact with a cold object, it loses heat until it reaches the temperature of that cold object. Heat is energy that is transferred between objects. The temperature of an object is related to its kinetic energy - increasing the temperature increases the mass in the kinetic energy equation. Only kinetic energy can be transformed into heat energy.
