How many joules of energy were added to the stockpot?

How many joules of energy were added to the stockpot? The heating rate was 30 joules per minute. A total of 150 J was added to the stockpot in 5 minutes.

What is the value of specific heat of water?

approximately 4.2 J/g°C.
For liquid at room temperature and pressure, the value of specific heat capacity (Cp) is approximately 4.2 J/g°C. This implies that it takes 4.2 joules of energy to raise 1 gram of water by 1 degree Celsius.

What is the relationship between heat energy and temperature?

Summary. The thermal energy, or heat, of an object is obtained by adding up the kinetic energy of all the molecules within it. Temperature is the average kinetic energy of the molecules. Absolute zero is the temperature where molecular motion stops and is the lowest possible temperature.

What is the specific heat of mercury?

Specific heats and molar heat capacities for various substances at 20 C

Substance	c in J/gm K	c in cal/gm K or Btu/lb F
Tungsten	0.134	0.0321
Zinc	0.387	0.0925
Mercury	0.140	0.033
Alcohol(ethyl)	2.4	0.58

How do you find the c of a calorimeter?

We can determine Ccal by adding a known amount of heat and measuring the temperature change. The easiest way to add a known amount of heat is to add hot water to a calorimeter filled with cold water. Add 50.0 g of water which is at 100.0 °C to our calorimeter which contains 50.0 g of water at 23.0 °C.

What is CP and CV of water?

Specific heat is the energy required to raise the temperature of a unit mass of a substance by one degree. In thermodynamics, there are two kinds of specific heats: Cv (specific heat at constant volume) and Cp (specific heat at constant pressure).

What is specific heat of air?

At 300 K (27oC) , the specific heat of air is 1.005 kJ/kg⋅K .

What are the 3 ways heat can be transferred?

There are three ways heat is transferred into and through the atmosphere:

• radiation.
• conduction.
• convection.
