A bath tub is filled with 100 liter of water at 25 degrees celcius. How long do you stir the water witha teaspoon for the temperature to be 100 celcius.
To solve this problem, we need to know the rate at which the temperature of the water increases when stirring with a teaspoon. It is also important to note that other factors, such as the initial temperature of the teaspoon, will affect the heat transfer.
Unfortunately, we cannot provide an exact answer without additional information. However, I can give you a general outline of the approach to find the time required.
1. Determine the heat transfer rate: The heat transfer rate depends on various factors, including the surface area of the spoon, the thermal conductivity of the material, and the temperature difference between the spoon and the water. Without these values, we cannot provide an accurate rate.
2. Calculate the heat required: Determine the amount of heat needed to raise the temperature of the water from 25°C to 100°C. This can be calculated using the specific heat capacity of water (4.18 Joules/g°C) and the mass of the water (100 liters = 100,000 grams).
3. Estimate the stirring time: Once you know the heat transfer rate and the required amount of heat, you can estimate the stirring time. Divide the heat required by the heat transfer rate to get an approximate time.
Remember, this estimation is just a rough approximation, as many other factors can influence the actual time required to reach the desired temperature.
