What else can I help you with?
A thermos contains 150 cm3 of coffee at 85 C To cool the coffee you drop two 11-g ice cubes into the thermos The ice cubes are initially at 0 C and melt completely What is the final temperature of the?
The final temperature of the coffee in the thermos after the ice cubes melt can be calculated using the principle of conservation of energy. The heat lost by the coffee as it cools down will be equal to the heat gained by the ice cubes as they melt. By applying this principle along with the specific heat capacities of water and ice, you can determine the final temperature of the coffee.
Why is a thermos flask made of steel?
A thermos flask is made of steel because steel is a good insulator, which helps maintain the temperature of the liquid inside the flask for longer periods. Steel is also durable and easy to clean, making it a practical material for use in thermos flasks.
