Find the mass of copper that was heated from 32°C to 130°C by using
5400 joules of heat. Cou=.385 J/goC

143.12 g

Explanation:

From the question given above, the following data were obtained:

Initial temperature (T₁) = 32 °C

Final temperature (T₂) = 130 °C

Heat (Q) = 5400 J

Specific heat capacity (C) = 0.385 J/gºC

Mass (M) =?

Next, we shall determine the change in temperature of copper. This can be obtained as follow:

Initial temperature (T₁) = 32 °C

Final temperature (T₂) = 130 °C

Change in temperature (ΔT) =?

ΔT = T₂ – T₁

ΔT = 130 – 32

ΔT = 98 °C

Finally, we shall determine the mass of copper. This can be obtained as follow:

Change in temperature (ΔT) = 98 °C

Heat (Q) = 5400 J

Specific heat capacity (C) = 0.385 J/gºC

Mass (M) =?

Q = MCΔT

5400 = M × 0.385 × 98

5400 = M × 37.73

Divide both side by 37.73

M = 5400 / 37.73

M = 143.12 g

Therefore, the mass of copper is 143.12 g

chemical energy is stored in the chemical bonds of atoms and molecules. it can only be seen when it is released in a chemical reaction. when chemical energy is released, the substance from which the energy came is often changed into an entirely different substance.

this chemical reaction releases energy in the form of light and heat. chemical energy is the potential energy stored in the arrangement of atoms within molecules. breaking chemical bonds requires energy, while forming new chemical bonds releases energy.

the atp molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. in this form,energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.
