The objects may exchange heat between each other if they are in contact with each other.
The two objects will allow flow of heat between them if they have a difference in temperature from each other.
The heat will flow from higher temperature object to lower temperature object. The will reach a final temperature (common to each other) and then there will be no heat transfer between each other.

<span>To find: Sample error in percent
Solution:
Formula:
((Experimental value-theoretical value)/theoretical value)*100
where, theoretical value = 100°c
and, experimental value = 102°c (sample 1) 99.2°c (sample 2)
Sample error (in percentage) when boiling level was 102°c = ((102°c-100°c)/100°c)*100 = 2%
Sample error (in percentage) when boiling level was 99.2°c = ((99.2°c-100°c)/100°c)*100 = -0.8%</span>
