Answer:
Melting = endothermic, solid = exothermic
Explanation:
Ok so when ice cream melts, that requires heat, so it’s Endothermic. In order to melt it, it requires heat, heat is entering. When it becomes solid again, that is exothermic because it is losing heat in order to become cool again.
<span>The melting of ice is an event which is endothermic. Endothermic is the process when heat is transfer from the environment to the object. It happens when the onject absorbs the heat just like melting of ice. The ice is in solid form due to the compaction of positively charged atoms in it but when heat carrying electrons made contact to it, it melted.</span>
Deep under Jupiter's<span> clouds is a </span>huge<span> ocean of liquid metallic hydrogen. On Earth, hydrogen is usually gas. But on </span>Jupiter<span>, the </span>pressure<span> is so great inside its atmosphere that the gas becomes liquid. As </span>Jupiter<span> spins, the swirling, liquid metal ocean creates the strongest magnetic field in the solar system.</span>
