3. According to Newton's 'Law of cooling', the rate at which the heat is lost by a heated body is proportional to the difference in temperature between the body and the surrounding medium (when the temperatutre difference is very small). If a thermometer is taken outdoor, where the temperature is 6°C, from a room which temperature is 25C, and the reading drops 15°C in one minute, how long after its removal from the room will the reading be 8°C? after 45 secs what is the thermometer reading?

Heat Transfer 1. If you have a piece of extruded polystyrene insulation that has an R-value of 5 hr ft?.°F/Btu per inch [or RSI = 0.8805 (m² · K)/W)]. How many inches of extruded polystyrene do you need in your wall if you want it to have an R-value of 20 hr ft2.°F/Btu [or RSI = 3.522 (m² · K)/W)]? L= 4" 2. What is the transfer of vibrational energy due to collisions between neighbouring atoms and molecules in a solid called? a. Conduction b. Convection c. Radiation d. Latent Heat Radiant Energy 3. Absorptance is a measure of the relative amount of radiant energy absorbed by a surface. Does a shiny and smooth polished aluminum surface have a high absorptance (closer to 1), or a low absortptance (closer to 0)? Absorptance is a ratio of the radiation absorbed to the radiation received, and thus is dimensionless. What about reflectance? Are absorptance and reflectance related? 4. Emissivity is a measure of the relative amount of radiant energy emitted by a surface. Does a shiny and smooth…

Mercury is often used in thermometers. The mercury sits in a bulb on the bottom of the thermometer and rises up a thin capillary tube as the temperature rises. Suppose a mercury thermometer contains 8,380g of mercury and has a capillary that is 0.400mm in diameter. How far does the mercury rise in the capillary when the temperature changes from 0.0 0C to 25.0 0C?
