1. What quantity of heat is required to raise? the temperature of 450 grams of water
from 35°C to 85°C?

capacity of water is 4.18 J/g °C.

According to the law of conservation of mass, in a chemical reaction the total starting mass of all the reactants equal the total final mass of all the products. true or false?

In all trials, the magnitude of the final velocity for g1 + g2 was less than the magnitude of any initial velocity. as mass increased, what happened to the velocity? the velocity decreased. the velocity increased. the velocity of g1 + g2 could not be measured. the velocity was not affected by the mass increase.

What is the mass of the same rock on the earth
