How much heat is absorbed by 20g granite boulder as energy from the sun causes its temperature to change from 10°C to 29°C? The specific heat capacity of granite is 0.79 J/gºC.

Taking into account the definition of calorimetry, the heat absorbed is 300.2 J.

In first place, calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

Sensible heat is the amount of heat exchanged by a body without affecting its molecular structure. If you don't change the molecular structure, you don't change the state of aggregation. Since the molecular structure does not change, a change in temperature is observed.

In other words, sensible heat is the amount of heat that a body absorbs or releases without any changes in its physical state (phase change).

So, the equation that allows to calculate heat exchanges is:

Q = c× m× ΔT

where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.

In this case:

Replacing in the expression to calculate heat exchanges:

Q= 0.79× 20 g× 19 C

Solving:

Q= 300.2 J

In summary, the heat absorbed is 300.2 J.

Solution :

We know , heat absorb is given by :

Therefore , heat absorb is 300.2 J .

Hence , this is the required solution .

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

< > according to newton's third law of motion, forces always act in equal but opposite pairs. another way of saying this is for every action, there is an equal but opposite reaction.< >
