A piece of metal (50g) is boiled in water at 100°C and then transferred to a calorimeter with 80.0 mL of water at 22°C in it. The temperature of the water increases to 25°C. What is the specific heat capacity of the metal?

Frictional forces acting on an object are often converted into energy, which causes the temperature of the object to rise slightly.

When water dissociates, each water molecule splits into a hydroxide ion and a) h 3 o + b) a hydrogen atom c) a hydrogen ion d) h 2 o e) oh —
