What variable represents specific heat in the equation [tex]Q=m c \Delta T[/tex]?
A. The variable [tex]$c$[/tex]
B. The variable [tex]$T$[/tex]
C. The variable [tex]$Q$[/tex]
D. The variable [tex]$m$[/tex]

The equation is Q = m c Δ T .
Q is heat energy, m is mass, c is specific heat, and Δ T is the change in temperature.
Therefore, the variable representing specific heat is c .
The answer is A ​ .

Explanation

Understanding the Equation The problem asks us to identify which variable in the equation Q = m c Δ T represents specific heat. Let's break down the equation:

Identifying Variables



Q represents the heat energy transferred (usually measured in Joules).
m represents the mass of the substance (usually measured in kilograms).
c represents the specific heat capacity of the substance (usually measured in Joules per kilogram per degree Celsius).
Δ T represents the change in temperature (usually measured in degrees Celsius).


Determining Specific Heat From the definitions above, we can see that the variable c represents the specific heat capacity.

Examples
Imagine you're heating water in a kettle. The specific heat capacity tells you how much energy you need to add to raise the water's temperature by a certain amount. Different materials have different specific heat capacities; for example, water requires much more energy to heat up than metal. Understanding specific heat helps engineers design efficient heating and cooling systems, and it's also crucial in cooking and many other everyday applications.
