what are the units of \q\ in q = mcδt
a joules per gram degree celsius (j/g°c)
b grams (g)
c degrees celsius (°c)
d joules (j)

Question

Accepted Answer

# Explanation:
## Step1: Analyze the formula
The formula $Q = mc\Delta T$ is used to calculate heat energy.
## Step2: Determine the units of each variable
- $m$ (mass) has units grams ($g$).
- $c$ (specific heat capacity) has units $J/(g\cdot^{\circ}C)$.
- $\Delta T$ (temperature change) has units degrees Celsius ($^{\circ}C$).
## Step3: Calculate the units of $Q$
$$
\begin{align*}
\text{Units of }Q&=\text{Units of }m\times\text{Units of }c\times\text{Units of }\Delta T\
&=g\times\frac{J}{g\cdot^{\circ}C}\times^{\circ}C\
&=J
\end{align*}
