What is the final temperature of the aluminum can after heating water?

Click For Summary
SUMMARY

The final temperature of the aluminum can after heating water can be calculated using the principles of thermodynamics, specifically the conservation of energy. In this scenario, 1.0 g of water at 28 degrees Celsius is heated to 100 degrees Celsius and then vaporized, while the aluminum can, initially at 300 degrees Celsius, loses heat. The specific heat capacity of aluminum is 900 J/kg/°C, and the specific latent heat of water is 2.26 x 10^6 J/kg. The calculations involve determining the heat required to raise the water's temperature and then to vaporize it, which equals the heat lost by the aluminum can.

PREREQUISITES
  • Understanding of specific heat capacity and latent heat
  • Basic knowledge of thermodynamics and energy conservation
  • Ability to perform calculations involving heat transfer
  • Familiarity with units of measurement (Joules, kilograms, degrees Celsius)
NEXT STEPS
  • Calculate the heat required to raise the temperature of water from 28°C to 100°C using the formula Q = mcΔT
  • Determine the heat needed to vaporize water at 100°C using the formula Q = mL, where L is the specific latent heat
  • Apply the principle of conservation of energy to find the final temperature of the aluminum can
  • Explore the impact of heat loss to the surroundings in real-world scenarios

Homework Statement



1.0 g of water at 28 degree celsius is placed into a 200g aluminium can at 300 degree celsius. What is the temperature of the aluminium can after all the water vapourises? Given the specific heat capacity of aluminium, 900 J/kg/degree celsius and water, 4200 and specific latent heat of water, 2.26 x 10^6 J/kg assuming no heat is loss to the surrounding.

Homework Equations





The Attempt at a Solution



I am not sure how to go about when it comes to combined specific heat capacity. Do we simply add them up?
 
Physics news on Phys.org
Find the amount of heat needed to rise the temperature of 1 g of water from 28 degree celsius to 100 degree celsius.
Next find amount of heat needed to evaporate 1 g of water from 100 degree celsius to 1 g of steam at 100 degree celsius. Find the total amount of heat.
This much heat is lost by the aluminum can.
