CALCULATION

Specific Heat of Water = 4186 J/kg °C, Specific Heat of Iron = 452 J /kg °C, Specific Heat of Ice = 2093 J/kg °C, Specific Heat of Lead = 130 J/kg °C Latent Heat of Fusion = 3.34 x 105 J/kg, Specific Heat of Copper = 385.1 J /kg.°C Density of iron = 7.874 g /cm3 Density of copper = 8.95 g /cm3 2. Convert 403 K to °F temperature.

If you have 0.276 m of water at 25.0 °C in an insulated container and add 0.112 m³ of water at 95.0 °C, what is the final temperature T; of the mixture? Use 1000 kg/m² as the density of water at any temperature. T; = °C

2.2 kg of ice (solid phase of water) at -10°C is heated under atmospheric pressure. Answer the following questions. Use the following values for your calculation. specific heat of ice: 2.1 kJ/(kg °C) specific heat of water: 4.2 kJ/(kg °C) specific heat of vapor: 2.0 kJ/(kg °C) latent heat of fusion: 334 kJ/kg latent heat of vaporization: 2260 kJ/kg    How much heat is required to raise the temperature of the ice to melting point T = 0°C?  How much heat is required to change the phase of the ice to liquid water?  How much heat is required to raise the temperature of the liquid water to boiling point T = 100°C?

If 31.0 g of milk at a temperature of 4.05°C is added to a 260-g cup of coffee at a temperature 91.0°C, what is the final temperature of the mixture? Assume coffee has a specific heat of 4.19 ✕ 103 J/(kg · K) and milk has a specific heat of 3.93 ✕ 103 J/(kg · K).
