Description	The rate of heat flow between two systems is measured in watts (joules per second). The formula for rate of heat flow is \(\bigtriangleup Q / \bigtriangleup t = -K \times A \times \bigtriangleup T/x\), where \(\bigtriangleup Q / \bigtriangleup t\) is the rate of heat flow; \(-K\) is the thermal conductivity factor; A is the surface area; \(\bigtriangleup T\) is the change in temperature and \(x\) is the thickness of the material. \(\bigtriangleup T/ x\) is called the temperature gradient and is always negative because of the heat of flow always goes from more thermal energy to less).
