ice cream melts in the sun because when the heat of the sun get to the ice cream its starts to melt like ice.
Ice cream will melt faster than yogurt, as yogurt does not melt.
It depends on what temperature the room/place is. In summer, inside or out, it will always melt a lot quicker and if the temperatues are perticularly high, could melt as fast as 10-15 minutes. Same with winter, in the cold months it will melt slower. If you are outside and it is a cold winter, the ice cream may not melt at all. But if inside, it could take anything from 12mins to 1hr.
It depends on your ice cream maker. If you use a gel canister model, 20 minutes. Longer and your ice cream starts to melt. An ice and salt ice cream freezer can take a bit longer. Compressor ice cream makers take between 35-40 minutes. For more on the different kinds of ice cream makers and how they work, see The Ice Cream Maker (link below).
