# How much energy does it take to heat 346 g of steam at 100 degrees to steam at 110 degrees Celsius if the specific heat of steam is 2.01 J/g°C?

Use The Thermochem Equation

#### Explanation:

$q = m c \Delta t$

Where:
$q$ = energy used/gained
$m$ =mass of system being heated/cooled
$\Delta t$ =temp. change
$c$ = specific heat capacity

Based on the information given, we can calculate the $\Delta t$:

$\Delta t$ = final temp - initial temp
$\Delta t = 110 - 100$
Deltat = 10°C

We also know that:

$m$ = 346 g
$c$ = 2.01 J/g°C

So we can now sub everything into our equation:

$q = m c \Delta t$
$q$=(346g)(2.01J/g°C)(10°C)
$q$ = 6954.6 J
