Answer:

283549.68 J

Explanation:

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

Mass (M) = 2.7 Kg

Initial Temperature (T₁) = 5.4 °C

Final temperature (T₂) = 30.5 °C

Specific heat capacity (C) = 4184 J/KgºC

Heat (Q) =?

The amount of heat energy needed can be obtained as follow:

Q = MC(T₂ – T₁)

Q = 2.7 × 4184 × (30.5 – 5.4)

Q = 11296.8 × 25.1

Q = 283549.68 J

Thus, the heat energy needed is 283549.68 J

The evaporation of liquid water from the surface of Earth is an important step in the water cycle. How do water molecules obtain
Alex777 [14]
<span>Well, during the day, the water, as well as the surfaces surrounding the water, are heated by various thermodynamic processes: conduction, convection, radiation, etc. This in turn warms the water molecules in the lakes, streams, rivers, and oceans, thereby transferring heat (their kinetic energy) to the water molecules, which in turn receive that energy from the surrounding surfaces, or directly via radiation/insolation from the sun. When the water molecules attain enough energy, some of them attain enough energy to escape the surface of the liquid and enter the gas phase. Hence, as water is heated, more and more water molecules attain enough kinetic energy to enter the gas phase.</span>
