What is the total amount of heat absorbed by 100.0
grams of water when the temperature of the water is
increased from 30.0°C to 45.0°C?
A) 418 J
B) 6270 J
C) 12 500 J
D) 18 800 J

Option (B) 6270J

Explanation:

The following were obtained from the question:

M = 100g

T1 = 30°C

T2 = 45°C

ΔT = 45 —30 = 15°C

C = 4.18J/g°C

Q=?

Q = MCΔT

Q = 100 x 4.18 x 15

Q = 6270J

Therefore, the total amount of heat absorbed is 6270J

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
