Properties of Water and Heat Transfer

Question 1

Name the 4 properties of water?

Answer 1

1. SPECIFIC HEAT AND THERMAL CONDUCTIVITY
2. MECHANICAL EFFECTS
3. WATER RESISTANCE AND HYDROSTATIC PRESSURE
4. CHEMICAL EFFECTS (SOLUBILITY)

Question 2

Which creates more buoyancy and resistance, and why; salt water or fresh water?

Answer 2

SALT WATER
because it’s
HEAVIER THAN FRESH WATER
