Measure Heat Flow

cava chem 303 s2d37 4.02 Measuring Heat Flow

QuestionAnswer
Before the nature of the atom was discovered, scientists thought that a weightless, invisible fluid called [...] made objects either hot or cold. Before the nature of the atom was discovered, scientists thought that a weightless, invisible fluid called caloric made objects either hot or cold.
In 1783, Antoine Lavoisier proposed that caloric moved from [...] objects to [...] objects. In 1783, Antoine Lavoisier proposed that caloric moved from hot objects to cold objects.
The [...] energy of a substance is the combined motion of all the particles within it. The thermal energy of a substance is the combined motion of all the particles within it.
[...] is the transfer of thermal energy. Heat is the transfer of thermal energy.
If thermal energy is not moving from one object to another, you don't call it '[...]'. If thermal energy is not moving from one object to another, you don't call it 'heat'.
You only call thermal energy '[...]' when it's moving from one object to another. You only call thermal energy 'heat' when it's moving from one object to another.
[...] of molecules transfer thermal energy (not 'caloric'). Collisions of molecules transfer thermal energy (not 'caloric').
[...] energy: the internal kinetic energy of all the particles in any substance Thermal energy: the internal kinetic energy of all the particles in any substance
[...]: the measure of the thermal energy within any substance Temperature: the measure of the thermal energy within any substance
[...] measures the average kinetic energy of the particles in a substance temperature measures the average kinetic energy of the particles in a substance
[...]: the change in thermal energy of a substance Heat: the change in thermal energy of a substance
A [...] is the amount of heat it takes to raise one gram of water by one degree Celsius. A calorie (cal) is the amount of heat it takes to raise one gram of water by one degree Celsius.
A [...] is the common unit for energy outside of food. A joule (j) is the common unit for energy outside of food.
temperature measures the [...] of the particles in a substance temperature measures the average kinetic energy of the particles in a substance
[...] is measured by a change in temperature heat is measured by a change in temperature
A calorie (cal) is the amount of heat it takes to raise one gram of [...] by one degree Celsius. A calorie (cal) is the amount of heat it takes to raise one gram of water by one degree Celsius.
A calorie (cal) is the amount of heat it takes to raise one gram of water by [...] degree Celsius. A calorie (cal) is the amount of heat it takes to raise one gram of water by one degree Celsius.
The Calories on food labels (with a capital 'C') are actually [...]. The Calories on food labels (with a capital 'C') are actually kilocalories.
