Which of the following substances would show the smallest temperature change upon absorbing 2.35 kj of heat? (mts 2/10/2018) 27 g fe ; cfe = 0.449 j/goc 27 g h2o ; ch2o = 4.18 j/goc 27 g ethanol ; cethanol = 2.42 j/goc

Water.

Explanation:

Hello,

Based on the formula:

Δ

Solving for Δ, we state that:

=\frac{Q}{mCp}" alt="T" />=\frac{Q}{mCp}" />

Now, for each substance we get:

Δ

Δ

Δ

We sum up that the water shows the smallest temperature change. This could be also stated by know that the iron has the highest heat capacity.

Best regards.
