that's rightits 1.something.........i think its 1.15
i wish i got it before physic p3.....now its kinda useless
yahoooooooooooooothat's right
LOL! calm down!yahoooooooooooooo
I don't think so, areeba. because heat is not removed. you have to supply heat!
But guys after evaporation heat is lost right? remember molecules with higher energy escape the surface...and leave behind molecules with lower energy(cooler)?no because for evaporation energy is taken in not given out
Condensation is right, also freezing.But guys after evaporation heat is lost right? remember molecules with higher energy escape the surface...and leave behind molecules with lower energy(cooler)?
but during the process of change of state, it takes in heat. this is what is asked.But guys after evaporation heat is lost right? remember molecules with higher energy escape the surface...and leave behind molecules with lower energy(cooler)?
have a look http://en.wikipedia.org/wiki/Series_and_parallel_circuits
idk where you got the idea that voltage somehow magically divides in a parallel circuit
lol its aginst the simple rules of electronics
I think this is the ryt solution:
i drew HALF OF A SEMI CIRCLEI wrote diffraction because the waves at the right (I drew circular waves BTW) they reached P.
i meant "circular" waves and yeah that WAS semi circle and that's what i drewi drew HALF OF A SEMI CIRCLE
is it rite
i did this cuz it said to da right of sth...
u dont get mei meant "circular" waves and yeah that WAS semi circle and that's what i drew
Hi....I've a question in this http://www.xtremepapers.com/papers/CIE/Cambridge IGCSE/Chemistry (0620)/0620_s11_qp_31.pdfthat's right
in evaporation heat is lost from the liquid but the particles that actually changed state have absorbed energyBut guys after evaporation heat is lost right? remember molecules with higher energy escape the surface...and leave behind molecules with lower energy(cooler)?
this can be done by hydrating butene.Hi....I've a question in this http://www.xtremepapers.com/papers/CIE/Cambridge IGCSE/Chemistry (0620)/0620_s11_qp_31.pdf
q6 ai ......plz tell me the steps here.
Thanks in advance
yea but how to change petroleum to butane and butane to butene?this can be done by hydrating butene.
the conditions required are:
60atm
300 degrees celsius
and phosphoric acid as a catalyst
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
