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

irishboy123 · Answer

just re-arrange the formula and put the units in and you should see an answer that is like one given above

$$c = \frac{Q}{m ∆t} = \frac{J}{g \space{  } ^oC}$$
