Final answer:
To quantify heat, the units used are British Thermal Units (BTU), Celsius Degrees (°C), Fahrenheit Degrees (°F), and Kelvin Units (K). BTU is an Imperial unit and is used in the U.S. for heating appliances, whereas Celsius and Fahrenheit are temperature scales used to express temperatures with degrees.
Step-by-step explanation:
The units of measure used to quantify heat, such as feeling the heat with British Thermal Units (BTU), are:
- British Thermal Units (BTU)
- Celsius Degrees (°C)
- Fahrenheit Degrees (°F)
- Kelvin Units (K)
A British Thermal Unit (BTU) is a unit of energy in the Imperial system, defined as the amount of energy required to heat one pound of water by 1°F. Heating appliances in the U.S. are rated in BTU/hour, which is a unit of power and can be converted to Watts.
The SI unit for temperature is the kelvin (K), with degrees that are the same size as Celsius degrees, but the numerical scale is shifted up by 273.15 units. Fahrenheit degrees (°F) are commonly used in the United States, with specific points such as the freezing and boiling points of water defined on this scale. Lastly, Celsius degrees (°C) are used widely around the world, except in the United States, for measuring temperature.
Units such as the calorie and joule are also used to measure heat. A calorie is the quantity of heat required to raise the temperature of 1 gram of water by 1°C, while a joule is the SI unit of energy.
