Topic. Transfer of Heat  


Q. When we touch a metal spoon, it feels cold. why?

Ans. 

Metal spoons feel cold because they are good conductors of heat, transferring heat away from your hand quickly.

Q. How is thermal radiation helpful in plant growth? Infer your answer.

Ans. 

While thermal radiation itself isn't directly helpful for plant growth, it plays a crucial role in creating a warm environment for optimal plant development. It helps maintain warmth within the plant body, promotes enzyme activity, and accelerates metabolic processes. Additionally, it can stimulate germination and early flowering in some species. Therefore, thermal radiation, in conjunction with other environmental factors, indirectly contributes to healthy plant growth.

Q. Can we use the process of distillation for removing salt from water? Explain BK Business & Investment Ans.  Distillation is not an effective method for removing salt from water. In distillation, water is heated to its boiling point, turning into vapor, and then condensed back into liquid. Earn money on Instagram with these unique hacks However, salt has a higher boiling point than water, so it remains in the original container. To remove salt, other methods like reverse osmosis or desalination are more suitable, as they physically separate salt from water molecules. # How To Dress To Hide Belly Fat Sign Up & Get 100 $ instantly work from home ads
