Answer:

A

Explanation:

Im pretty sure it's A. I MIGHT be wrong so dont quote me on this. THis is what the internet says:

"Atomic Radius. Atomic radii decrease from left to right across a period and increase from top to bottom along a group."

Object A specific heat is 2.45 J/g C and object B specific heat is 0.82 J/g C. Which object will heat up more if they have the s
Artist 52 [7]

Answer: Object B will heat up more.

Explanation:

The formula for specific heat is as follows.

                  Q = m C \Delta T

Where,

                      Q = heat provided

                      m = mass

                      C = specific heat

            \Delta T = change in temperature

Now, both the objects have same mass and equal amount of heat is applied.

According to the formula, the equation will be as follows.

                      Q_{1} = Q_{2}

                  m C_{1}\Delta T = m C_{2}\Delta T_{2}

Cancel m from both sides, as mass is same. Therefore,

            C_{1} (T_{f} - T_{i})_A = C_{2}(T_{f} - T_{i})_B

Cancel out the initial temperature and put the values of specific heat, then the equation will be as follows.

             2.45 (T_{f})_A = 0.82(T_{f})_B

Therefore, from the above equation it can be concluded that the object with low specific heat will heat up more as its specific heat will be inversely proportional to its final temperature.

Hence, object B will heat up more.
