    Heating and Cooling Investigation Aim- to find out if different sized cans affect the temperature of 140ml of boiled water, when they are left alone to cool. In this experiment, I will be using two different sized cans (one 12cm tall holding 330ml and another 9cm tall holding 150ml). I will be seeing if each can keeps the boiled water warm for a period of time and testing to find out which one is the best. Fair Test To make this a fair test, I will have to do many things. Firstly

    The Effect of Insulation on the Rate of Cooling P PLANNING The Problem The problem which I intend to investigate is out if insulation affects the rate of cooling, and whether the amounts of insulation would affect the rate of cooling Scientific Background An insulator is any of various substances that blocks or slows down the flow of heat, they can only transfer energy slowly. Many materials make air as an insulator, because air is an excellent insulator. Air can reduce heat

    Cooling Rate of Certain Liquids Scientific Investigations Experiments to Determine the Cooling Rate of Coffee, when Milk should be Added and what Container should be Used The aim of the first experiment was to find out and record the cooling rate of coffee under three different conditions and thus showing when milk should be added assuming you have a phone call. The three different conditions were chosen because these were the most likely situations encounted by someone who is making a cup

    Investigation of the Cooling of a Liquid in Cups with Different Materials Aim: To investigate how a liquid cools down in cups with different materials. Prediction: The factors which will affect the amount of heat loss are: § Material of the cup – Conduction § Colour – Radiation § Surface area of cup § Amount of water (surface area:volume ratio) § If the cup has a lid or not – Convection and Evaporation § Room temperature § Thickness of the cup § Temperature of the liquid

    The Effects of Colours and Radiation on the Rate of Cooling of Tap Water Aim: To investigate radiation and the rate at which it cools ordinary tap water according to the colour of insulation. Apparatus needed: · Several Standard 250ml glass beakers (to be replaced after each test) · A kettle (to heat the water) · A square of bubble-wrap (to sit under the beaker to insulate it from the floor) · A Thermometer · A stopwatch · Safety Goggles (due to handling very hot

    THERMOELECTRIC COOLING In thermoelectric cooling Peltier’s effect is used to cause heat flux between the junctions of different types of materials. A Peltier heater/cooler transfers heat from one side of the device to the other by consuming electrical energy. This device is also known as a Peltier device, Peltier heat pump, solid state refrigerator, or thermoelectric cooler (TEC). Since there are more economical and easy ways of achieving cooling, Peltier’s devices are mostly used for cooling purposes

    exposed soil exists, the majority of the sun's energy is absorbed by urban structures and asphalt. Hence, during warm daylight hours, less evaporative cooling in cities allows surface temperatures to rise higher than in rural areas. Additional city heat is given off by vehicles and factories, as well as by industrial and domestic heating and cooling units. At night, the solar energy, which is stored as vast quantities of heat in city buildings and roads, is released slowly into the city. The dissipation

    large amount of cooling was done by putting the compound in liquid helium. Helium, which is usually a gas, liquefies when its temperature drops to 4 K. Once the material had cooled to that temperature, it became a superconductor. However, using liquid helium to cool down material has been a problem. Liquid helium is very expensive, and the cooling equipment is very large. In the past, there was no economic incentive to replace ordinary conductors with superconductors because the cooling costs for superconductors
