1. What definition of heat and temperature?

2. What formula of heat and temperature?

3. What instrument to measure of heat and Temperature?
4. What unites of heat and temperature? ​


Sagot :

Answer:

1. Heat describes the transfer of thermal energy between molecules within a system

2. The quantitative relationship between heat transfer and temperature change contains all three factors: Q = mcΔT, where Q is the symbol for heat transfer, m is the mass of the substance, and ΔT is the change in temperature. The symbol c stands for specific heat and depends on the material and phase.

3. Thermometer

Two classes of instruments are employed for the measurement of heat, namely, thermometers and pyrometers. Thermometers are only employed to measure comparatively low temperatures, and we shall confine our remarks entirely to this class in the present article.

4.Heat and temperature are two different but closely related concepts. Note that they have different units: temperature typically has units of degrees Celsius

Answer:

1. Heat describes the transfer of thermal energy between molecules within a system and is measured in Joules. Temperature describes the average kinetic energy of molecules within a material or system and is measured in Celsius (°C), Kelvin(K), Fahrenheit (°F), or Rankine (R).

2. The quantitative relationship between heat transfer and temperature change contains all three factors: Q = mcΔT, where Q is the symbol for heat transfer, m is the mass of the substance, and ΔT is the change in temperature.

The Measurement of Heat with the Thermometer. Two classes of instruments are employed for the measurement of heat, namely, thermometers and pyrometers.

4.Heat and temperature are two different but closely related concepts. Note that they have different units: temperature typically has units of degrees Celsius ( ∘ C ^\circ\text C ∘Cdegrees, start text, C, end text) or Kelvin ( Kstart text, K, end text), and heat has units of energy, Joules ( Jstart text, J, end text).
