text: how much additional heat in joules is required to warm the water to 100 degrees celsius, its boiling temperatu physical science student estella uses an electric tea kettle to disinfect her apartment freezer with steam made from frost ice. she stuffs 2.0kg of frost ice into her kettle. the ice has an initial temperature of -20 degrees celsius. the specific heat of ice is=2100j/kg degrees celsius. the specific heat of water is=4200 j/kg degrees celsius. the specific heat of steam is =2100j/kg degrees celsius. the heat fusion of water is 335,000 j/kg degrees celsius. the heat of vaporization of water is= 2,260,000 j/kg degrees celsius. please show work on all problems. just use this formula:  q = (+-)ml  (sign depends on if it's fusion or vaporization)  where (m) is in kg and (l) is in j/kg or kcal/kg  and this:  q = m c (t-t)  where m is kg, c is specific heat and t is final temperature and t is initial temperature
