How much heat energy is required to raise the temperature of 0.358 kg of copper from 23.0 ∘c to 60.0 ∘c? the specific heat of copper is 0.0920 cal/(g⋅∘c) .

1.22 × 10³ cal

Explanation:

Given data

We can calculate the heat (Q) required to raise the temperature of 0.358 kg of copper from 23.0°C to 60.0°C using the following expression.

Q = c × m × ΔT

Q = (0.0920 cal/g.°C) × 358 g × 37.0°C

Q = 1.22 × 10³ cal

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
