How much heat is required to raise the temperature of 91.5 g of water from its melting point to its boiling point? Express your answer numerically in kilojoules. Can someone answer this for me in decimal form?

38.2836 kJ

Explanation:

Mass = 91.5g

Initial Temperature = melting point = 0 C = 273 K (upon converting to kelvin)

Final Temperature = Boiling point = 100 C = 373 K

Heat = ?

They are related by the equation;

H = mCΔT

ΔT = Final - Initial Temperature = 373 - 273 = 100 K

C = specific heat capacity = 4.184 J /gK

H = 91.5 * 4.184 * 100

H = 38283.6 J

To convert to kilojoules, divide by 1000. This leaves us with;

H = 38283.6 / 1000 = 38.2836 kJ

chemical digestion occurs in the stomach were hcl and pepsin forms chyme, the mouth in which salivary amylase breaks down starch to form bolus, and the small intestine specifically the duodenum.

girl imma just put my comment here because i need a couple point okurrttt
