- Homework Statement
- what is the numerical value of the ratio ?
- Relevant Equations
- Q=mcθ
Q=mc
the answer is 1/2 , but when I did the working out, I got 2/1.. so I'm quite confused
then are you able to explain the answer key ?Orodruin said:The ratio has physical dimension. You therefore cannot assign a dimensionless numerical value.
The question is ill posed.ellieee said:then are you able to explain the answer key ?
how ..? isn't specific heat capacity = mcθ and heat capacity = cθ?Orodruin said:But with regards to how the question (being ill posed) wants you to do things ...
You have taken heat capacity / specific heat capacity instead of specific heat capacity / heat capacity.
No.ellieee said:isn't specific heat capacity = mcθ and heat capacity = cθ?
Specific heat capacity, also known as specific heat, is the amount of heat required to raise the temperature of one unit of mass of a substance by one degree Celsius or Kelvin.
Specific heat capacity is a measure of the amount of heat required to raise the temperature of a specific amount of a substance, while heat capacity is a measure of the amount of heat required to raise the temperature of an entire object.
The specific heat capacity of a substance is affected by its chemical composition, molecular structure, and physical state (solid, liquid, or gas).
Specific heat capacity is important in thermodynamics because it helps determine the amount of energy needed to change the temperature of a substance, which is crucial in understanding heat transfer and energy conservation.
Specific heat capacity is typically measured by conducting experiments in which the amount of heat added to a substance and the resulting change in temperature are recorded. The specific heat capacity can then be calculated using the equation Q = mcΔT, where Q is the heat added, m is the mass of the substance, c is the specific heat capacity, and ΔT is the change in temperature.
