A perfectly insulated container is filled with water at a temperature of 90oC. A marble with a temperature of 50oC and a surface area of 0.003 m2 is dropped into the water. The convection coefficient of the water is 150 W / m2 K. What is the rate of heat transfer from the water to the marble?

explanation:

wind is defined by the direction it blows from.   for example, a wind blowing from north to south is called a northerly wind.

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary 

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
