.Write out your givens and your unknown(s). Do you know which formula(e) to use? Is there a chapter in your text you've read over and considered?Zeitgeist said:A 2.0 kg bag of ice is used to keep a cooler of pop cold for 5.5 h. If the ice had an initial temperature of -4ºC and, after 5h, was liquid water with a temperature of 3ºC, find the power of energy absorption.
Any help would be great. I don't know where to start
The energy absorption of a 2.0kg bag of ice can be calculated by multiplying the specific heat capacity of ice (2.108 J/g·°C) by the mass of the ice (2.0kg) and the change in temperature (in °C).
Calculating the energy absorption of a 2.0kg bag of ice can help determine the amount of energy needed to melt the ice, which can be useful in various situations such as designing refrigeration systems or planning for energy consumption.
The specific heat capacity of ice is 2.108 J/g·°C. This means that it takes 2.108 joules of energy to raise the temperature of 1 gram of ice by 1 degree Celsius.
The mass of the ice directly affects its energy absorption. The larger the mass, the more energy is required to raise the temperature of the ice by a certain amount.
The accuracy of the calculation of energy absorption can be affected by factors such as the accuracy of the specific heat capacity of ice, the initial temperature of the ice, and the efficiency of the system used to transfer energy to the ice.
