2 points 7. Given the following specific heats of energy, if the materials were left
out in the sun for 2 hours, which material would be the hottest? *
Material A: 2.03 J/gC
Material B: 0.71 J/gC
Material C: 0.89 J/gC
Material D: 0.45 J/gC

Material D as its specific heat is the smallest.

Explanation:

Hello.

In this case, since the specific heat is defined as the energy required to increase (or decrease) 1 gram of a material by 1 °C, we can infer that the smaller the specific, the less energy is required for such temperature change, therefore, since material D needs 0.45 J of energy to increase the temperature of 1 g by 1 °C we can see that it will become the hottest as it has the smallest specific heat among the other ones.

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
