The Effect of Different Types of Insulation on Heat Retention Aim I am going to investigate the effect of different types of material on heat retention. "Which of the four materials‚ cotton‚ foam‚ aluminium foil and bubble wrap‚ is the best insulator?" Hypothesis The four materials tested in this experiment are cotton‚ foam‚ aluminium foil‚ and bubble wrap. Materials that are good insulators will absorb heat slowly and therefore the water inside the cup will stay warm for

bacteria. Physical Methods Heat is a measure of energy in terms of quantity. The quality of being hot; high temperature: "it is sensitive to both heat and cold". A calorie is the amount of heat required to raise 1 gram of water 1°C (based on a standard temperature of 16.5 to 17.5°C). Conduction is the transfer of heat between materials that contact each other. Heat passes from the warmer material to the cooler material. For example‚ a worker’s skin can transfer heat

under steady conditions‚ and determine the rate of heat loss from the steam through the pipe. Assume that heat transfer is one-dimensional and there is no heat generation. The general equation can be expressed as: ( ? ?? )?( ) = 0 ?? ?? 2. Consider a 0.8m high and 1.5 m wide double-pane window consisting of two 4mm thick layers of glass (k = 0.78 W/m.oC) separated by a 10 mm wide stagnant air (k = 0.026 W/m.oC). Determine the steady rate of transfer through this double-pane window and the temperatures
