... heat will continue to flow until the temperature of the two objects has equalized, or reached the same temperature. For example, suppose you place an ice cube in a glass of water. Because the water is warmer than the ice, heat flows from the water to the ice until the two reach the same temperature. ...

Joule`s Law and Heat Transfer Name
... To do this we need to measure the amount of electrical energy we supply and the amount of heat energy the water, calorimeter-cup, and heater gains. Then neglecting heat loss to the room, we could find the relationship between calorie and Joule. Electrical energy, E is given by: E = I V t; where I = ...

Heat wave
A heat wave is a prolonged period of excessively hot weather, which may be accompanied by high humidity, especially in oceanic climate countries. While definitions vary, a heat wave is measured relative to the usual weather in the area and relative to normal temperatures for the season. Temperatures that people from a hotter climate consider normal can be termed a heat wave in a cooler area if they are outside the normal climate pattern for that area.The term is applied both to routine weather variations and to extraordinary spells of heat which may occur only once a century. Severe heat waves have caused catastrophic crop failures, thousands of deaths from hyperthermia, and widespread power outages due to increased use of air conditioning. A heat wave is considered extreme weather, and a danger because heat and sunlight may overheat the human body.
