What is the specific heat of a substance if 1560 cal are required to raise the temperature of a 312-g sample by 5 degrees celsius?
A) 0.033 cal/g*C
B) 0.33 cal/g*C
C) 0.99 cal/g*C
D) 1.33 cal/g* C

0.33 cal/g*C

Explanation:

The amount of heat required is determined from the formula

q

=

m

c

Δ

T

,

where

q

is the amount of heat transferred

m

is the mass of the substance

c

is the specific heat capacity of the substance

Δ

T

is the change in temperature

q

=

1560 cal

m

=

312 g

Δ

T

=

15 °C

c

=

q

m

Δ

T

=

1560 cal

312 g × 15 °C

=

0.33 cal⋅g

-1

°C

-1

the answer would be a

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
