Question

State the dimensions of pressure and heat​

Answer 1

Explanation:

pressure = N/m2 = force / area

Dimension of Pressure =[M¹L-1 T-2]

Dimension of heat = [M¹L²T-2]

Answer 2

The SI units for pressure are Newtons per square metre (N/m2) or Pascals, which are units of force per unit area (Pa). Psi (pounds per square inch) and atmospheres are additional pressure measurement units (atm).

• Energy, which has SI units of Joules, can be used to express the dimensions of heat (J). Heat is the thermal energy that is transferred from one thing to another when their temperatures are different.
• The temperature differential and the thermal conductivity of the materials involved both influence how much heat is transported.
• How much heat is necessary to raise the temperature of a substance depends in part on that substance's specific heat capacity.
• Specific heat capacity is measured in energy per kilogramme per degree of temperature (J/kg*K).
