B. Hot water The specific heat capacity of water is 4.186J/g °C
Calculate the temperature change when 8000 j of heat is added to 3g of water.
Use the equation q=mcAT
C. Specific heat capacity
Water has a specific heat capacity of 4.186J/g °C
Concrete has a specific heat capacity of 0.880 J/g °C
If a kg of water and a kg of concrete sit out in the sun on a hot day which one will have a change of temperature faster?

Explain why?

The heat capacity measures the amount of heat necessary to raise the temperature of an object or system by one degree Celsius.

LEARNING OBJECTIVES

Explain the enthalpy in a system with constant volume and pressure

KEY TAKEAWAYS

Key Points

Heat capacity is the measurable physical quantity that characterizes the amount of heat required to change a substance’s temperature by a given amount. It is measured in joules per Kelvin and given by.

The heat capacity is an extensive property, scaling with the size of the system.

The heat capacity of most systems is not constant (though it can often be treated as such). It depends on the temperature, pressure, and volume of the system under consideration.

Key Terms

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
