Every substance has a specific value of heat required to change the temperature of 1 gram of the substance by 1 degree Celsius. Specific heat is found by using the equation Q=mcΔt, where Q represents heat in joules, m represents mass in grams, Δt is the change in temperature in Celsius, and c is the coefficient constant for a substance. Find the units for the coefficient c.

A)

c=J·g·°C

B)

c=J·g/°C

C)

c=J/g·°C

D)

c=g·°C/J
