Are you sure about black surfaces emitting the least radiation? Black surfaces are good absorbers and emitters of heat. Anyways, could we also include the topic of specific heat capacity in question 6 (b) as the road has a comparatively smaller value of specific heat capacity when it is compared to h20
Black bodies radiate the most heat and reflect the least light while white radiates the least heat and reflects the most light. Since we are talking about radiation in this question, mentioning about heat capacity might not give you the mark(s). The answer given should be relevent to the whole question. Hope it's clear.

Qn 5
I think boiling point would sound much better if you said … The constant temperature at which a liquid changes into a gas
yeah maybe it would be 😀
@Joshua chadd alright no problem 😄
Love u mate, love fro m aussie
Love u G, love fro m Aotearoa

@@scienceandmathpapers Alright so we need to give our answers that relate to that specific question right ? If so, yep thanks for making it clear 😇😇
thanks,will you give any suggestions on math papers
Hey 👋, Just make sure you clear all topics one by one with solving topic wise papers alongside ~ Hope it helps.
@@scienceandmathpapers thanks again
Nice Video Sir.😀
Is it okay if i got my answer as 1600000Pa in question 2 c)
That's the answer for 2 b
Mhmm.. K bye
