need help with these 3 heat questions in science class....?

Question

1) Equal masses of 2 substances absorb the same amount of heat. The Temp of substance “A” increases twice as much as the Temp of substance “B”. Which substance has higher specific heat? Xplain
2)The temp of a person w/ a high fever can be lowered w/ a sponge bath of isopropyi alcohol (C3H7OH). The heat of
vaporization of this alcohol is 11.1 kcal/mol.
A) How many kilocalories of heat are removed
from a person's skin when 175 g of isopropyl
alcohol evaporates? How many kilojoules?
B)How many kg of water would this
energy loss cool in lowering the temp
from 40.0 C to 36.0 C?
3)A ice cube @ 0 degrees C is dropped into 30 g cup of water thats 45 degrees. The ice melts, the temp of the water is 19.5 degrees C. What's the mass if the ice cube?

Answer 1

1) Substance B has the higher specific heat because Q=mcΛT
2) and 30 sorry can't answer just too much work
