Apr 21st
Query by tzier187: A chemistry question about ice changing to h2o and the volume of joules of warmth vitality necessary? How many joules of heat energy are required to change 175.0g of ice at .00 degrees Celcius to liquid h2o at 50. degrees Celcius?
Finest reply:
Remedy by MaureenHeat electricity = mass of water x specific heat capability of h2o x modify in temperature
Mass = 175g = .175 Kg Specific Warmth Capacity = four.18 kJ/kg/oC Change in Temp = fifty – = 50
Put these into the equation and you get
.175 x 4.18 x 50 = 36.575 kJ

Question by Andy T: how much energy needed to melt 10g of ice to h2o? Please display me the step to clear up the problem
Additionally, what if only 8g of ice melted to h2o
and 2g of ice remained
how significantly vitality was tranfered, write steps please.
