A.) Boiling of milk produces heat on the outside which is exothermic

ratelena [41]3 years ago

Answer: Option (a) is the correct answer.

Explanation:

A process in which heat is absorbed by the atoms of a substance is known as endothermic process. Here, energy of products is more than the energy of reactants.

Whereas a process in which heat is released by the atoms of a substance is known as exothermic process. Here, energy of reactants is more than the energy of products.

So, when milk boils then energy is releasing in the form of steam. When wax melts then it means heat is absorbed by wax molecules.

When water freezes then also energy is absorbed due to which molecules are coming closer to each other.

Whereas evaporation and heating of water will are also endothermic as heat is absorbed in both the cases.

Thus, we can conclude that boiling of milk  is an example of an exothermic process.

How does a greenhouse keep radiant energy from escaping?
Rina8888 [55]
Greenhouse effect is the process of trapping sun radiation in the earth surface, so as to make the planet warm. It is a natural phenomenon in which sun rays that enters the earth surface are re-radiated into the earth surface causing the heat trap in the earth.
In similar manner, green house also trap radiation inside the glass house. The sun rays once reach inside the glass house, strike on plants and objects and reflected back. For entire radiation to escape from the green house, the heat flow between the two points must be proportional to the temperature difference and thermal conductivity. The glass of which the green house are made up, have low thermal conductivity. So, temperature must rise inside glass house so to maintain the heat flow rate of incoming and outgoing radiation.
The green house glass are insulated and they trap the infrared emitted by the objects inside the green house from escaping outside. Since the infrared have longer wave lengths, it is released slowly. 

Also, the thermal energy inside the glass house are transferred by convection process. But the glass walls and roof act as insulator, keeping the radiant energy from escaping outside the green house.<span />
