Question 1

spefific heat is

Answer 1

heat transferred over (mass times the change in temperature) or Q=MCAT

Question 2

calorimeter is

Answer 2

equipment used to measure the heat that is transferred during a reaction or physical process

Question 3

electrolyte

Answer 3

ability to conduct electricity because the solute ionizes

Question 4

perfect by mass formula

Answer 4

mass of solute (what’s being dissolved) over mass of solution (total) all times 100 to get a percent

Question 5

percent by volume

Answer 5

volume of solute over volume of solution all times 100
