If you heated 2.5 kg of water using 100 kcal of energy, then what would be the temperature increase of the water (degrees C)? 250 degrees C

40°C.

Explanation:

A calorie is defined as the amount of energy needed to raise the temperature of 1 gram of water through 1 °C. In the same way, a kcal would be defined as the amount of energy needed to raise the temperature of 1 kilogram of water through 1 °C.

Based on this definition, 100kcal will increase the emperature of the water in:

100kcal / 2,5kg = 40°C

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
