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. A chair is placed several feet from a fire in a fireplace. The fireplace has a glass screen. The
1. What does it mean if water has a higher specific heat capacity than oil? It requires more energy to raise its temperature by the same amount. 2. What is the difference between thermal energy and temperature? Temperature is a measure of the average kinetic energy of the molecules present. Thermal
There are three key ways that heat transfers. With _____ objects, heat transfers when the objects come into direct _____ with other things. This is known as _____. Liquids and gases are different. Because these two states of matter flow, or are _____, heat transfer happens when
As you read about the three types of heat transfer, pay attention to: What the heat is moving through (solids, liquids and gases, or empty space) How the heat is being transferred (touch, currents, or waves)
1. How many joules of heat are required to raise the temperature of 550 g of water from 12.0 oC to 18.0 oC? 2. How much heat is lost when a 64 g piece of copper cools from 375 oC, to 26 oC? (The specific heat of copper is 0.38452 J/g x oC). Place your answer in kJ. 3. The specific heat of iron is 0.4494 J/g x oC.
Latent heat and Specific heat capacity questions. 1. How much water at 50°C is needed to just melt 2.2 kg of ice at 0°C? 2. How much water at 32°C is needed to just melt 1.5 kg of ice at -10°C? 3. How much steam at 100° is needed to just melt 5 kg of ice at -15°C? 4. A copper cup holds some cold water at 4°C.
