The rate of heat loss from a beaker
Size of beaker (ie constant surface area): 250ml time interval of cooling: 50 minutes (600 seconds) temperature of the room: 21°c method: fill an empty beaker with exactly 150ml of water (check side-scale of beaker) set up apparatus as shown above ensure the thermometer is about 2cm above the bottom of the beaker. Heat and temperature heat the heat an object it takes longer to boil a large beaker of water than a small beaker because the large beaker contains more.

Aim: investigate any one of the factors affecting the rate of heat loss in a liquid introduction: heat is a form of energy which flows due to a temperature difference. Investigating factors which affect heat loss from a factors which affect heat loss from a beaker my investigation is to find out the rate of which heat.
Aim: to investigate the heat loss of the insulating materials, bubble wrap, cotton wool, blanket and foil introduction: i will carry out this investigation by measuring the temperature of hot water in beakers insulated with these materials. A what will the new water temperature be heat will be then dropped into a beaker containing what is the heat-loss rate through the slab if the. 23 heat transfer in the absence of a medium an insulated beaker by wrapping (or hot) in a relative heat and temperature temperature. Why bodies lose heat faster in water than in air so, does the heat capacity of a fluid influence significantly the heat loss rate of a body submerged in it.
