Title: physics p1 question-demanding
Post by: mr_scholes on June 08, 2009, 03:46:11 pm
In an experiment, a piece of melting ice and a beaker of boiling water are in a laboratory which is
at 20 °C.
What is happening to the temperature of the melting ice and of the boiling water?


     temperature of the melting ice                 temperature of the boiling water
A           constant                                                   constant
B           constant                                                   increasing
C           increasing                                                 constant
D           increasing                                                  increasing

Definately the answer is A becoz when the change of state is taking place so the temp remains constant

hope it helped dont forget to + Rep thnxx

ans 100% a
bcz during melting n boiling d avg k.e of d moecules remain same therefore temp constant the enery is used to inc p.e tht breaks d bond between d molecules
hope i helped

100% A bccuz whilechange of state is takin place temp stays constant bcuz the bond are been broken
hoep that helps + rep if soo :)
