Types of Heat Transfer •Conduction - This is a flow of heat by direct contact. Heat travels from a warmer object toward a colder object. A pan warming on a stove is an example. •Convection - This is a transfer of heat by mixing a fluid, such as a gas or liquid. Examples include boiling water and when warm water mixes with cold water.
In each of the following situations, identify the method of heat transfer taking place (conduction, convection, radiation). More than one process may be occurring. 1. Hot coffee is stirred with a spoon; the spoon gets hot due to... 2.
Conduction is how heat travels between objects that are touching. Conduction travels fastest through solids, but liquids and gases can also conduct heat. Some materials, like metal, can conduct heat very quickly, while other materials (like plastic or wood) conduct heat very slowly. Convection is how heat travels through fluids – liquids and ...
In each of the following situations, identify the method of heat transfer taking place. Write conduction, convection, or radiation on the line next to the statements. Choose
Specific heat is defined as the amount of heat (in _____) needed to raise ____ gram of a substance ____˚C. Every substance has its own specific heat depending on the bonds and forces it has. 1. At the park, why do you tend to steer clear of metal benches and prefer wooden picnic benches? Which has a lower specific heat? 2.
Heat Transfer Worksheet. Specific heat capacity. 1. (a) How much energy is lost when 50 g of iron cools from 45°C to 15°C? (b) Find the specific heat capacity of gold if 108 J of energy raise the temperature of 9.0 g from 0°C to 100°C. (c) Find the amount of energy required to raise the temperature of 1000 kg of sea-water through 40K. 2.
• explain how heat moves from one place to another including how cooler materials can become warmer and vice versa. • describe how heat moves by conduction, convection, and radiation.
