The equation for heat transfer is $$H\ =\ m\times c\times\Delta T$$  What is represented by  $$m$$  ?

The equation for heat transfer is $$H\ =\ m\times c\times\Delta T$$  What is represented by  $$c$$  ?

We know inuitively that it takes more energy to boil two kettles of water than one kettle. Mathematically, we say this as:

When making a kettle of tea, we start with room temperature water instead of cold water because

We had some nails and water that were both too hot too touch. The nails cooled down faster because:

The sand at a beach gets very hot during the day, and cools down rapidly at night. The water stays close to the same temperature, because

Something that has a high specific heat capacity is likely to:

Something that has a low specific heat capacity is likely to:

The equation for heat transfer is $$H\ =\ m\times c\times\Delta T$$  Using this equation, figure out how much heat is required to warm up 2000 g of water from 20 degree C to 100 degrees C. Conveniently, the specific heat capacity of water is 1 cal/gram/degree C

The equation for heat transfer is $$H\ =\ m\times c\times\Delta T$$  Using this equation, figure out how much heat is released when 100 grams of olive oil cool by 40 degrees C. The specific heat capacity of olive oil is c = 0.5 calories/gram/degree C.
