Without an agent doing work, heat will always flow from a hotter to a cooler object. Two objects<span> of different temperature always interact. There are three different ways for heat to flow from one object to another. They are conduction,</span>convection<span>, and radiation ^^Answer for 3 and for question 4 is
The hot cup has more air flowing around it to cool it down meanwhile the cold cup has COLD air flowing around it so it would jst do nothing in a result of the cold cups cool temputure to increase
I really hoped this helped and have a great day :)</span>
