Specific heat is the amount of heat required to raise the temperature of a material by 1°c per what unit?

The heat required to raise the temperature of the unit mass of a given substance by a given amount (usually one degree).

or C. Mass if you're on plato

Per unit mass

Explanation:

When some heat energy "Q" is given to an object of mass "m"  to raise its temperature by "ΔT", then the energy is given as

Q = m c ΔT

where c = specific heat of the object

rearranging the above equation

c = Q/(m ΔT)

for "1 °C" rise of temperature , ΔT = 1

So specific heat is defined as amount of heat required to raise the temperature by 1 °C per unit mass of the object.

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
