The temperature difference between a cup with a lid and without a lid can be calculated using calorimetry. By comparing the heat lost by the coffee in each cup, we can find the temperature difference.
The temperature difference between a cup with a lid and a cup without a lid can be calculated using calorimetry.
In calorimetry, the heat lost by one object is equal to the heat gained by another object. In this case, we can calculate the heat lost by the coffee in each cup and compare them to find the temperature difference.
For example, let's say the cup with a lid had a starting temperature of 95.0°C and a final temperature of 45.0°C.
The cup without a lid had the same starting temperature of 95.0°C.
Using the formula Q = mcΔT, where Q is the heat, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature, we can calculate the heat lost by the coffee in each cup.
By subtracting the heat lost by the coffee in the cup without a lid from the heat lost by the coffee in the cup with a lid, we can find the temperature difference between the two cups.
