HI THIS ISNT HELP AND IM SORRY BC I DONT KNOW BUT PEEP GANG WYAAA
Explanation:
Ответ:
What material would you use: I would use a beaker, water, heated metal
What would you measure: Measure the changes in temperature before and after pouring the metal.
What results would you expect: Whether Thermal Equilibrium has occurred or not.
What if the results were different; what would that indicate : The Beaker might absorb some of the heat causing an error in the reading.
Explanation:
step 1: Take a well insulated beaker and pour water of known mass in it.
step 2: Record its initial temperature.
step 3: Place heated metal into the beaker and make sure that the beaker is tightly packed so that no heat escapes from the beaker.
step 4: Record temperature of the beaker at different intervals and after temperature has become constant ( No heat is being gained) , note the final temperature
In end we will check whether thermal equilibrium is established or not.
heat lost by the metal = heat gained by water + heat gained by the beaker
Possible Error:
There might be disparities in the values acquired as the beaker will absorb some heat.
