Thanks for the fun question.

Frozen yogurt has a melting point at about the same temperature as ice, at 32 degrees Fahrenheit or 0 degrees Celsius. While ice cream is usually frozen at about 22 degrees F, frozen yogurt is frozen at a colder temperature of 18 degrees F.

This means at room temperature (approximately 70 degrees F), frozen yogurt will keep its consistency for a bit longer than ice cream.

Depending on how much yogurt you have, you could expect it to take even up to an hour before you have fully liquid yogurt.

That depends on the temperature of the room and the temperature of the frozen yogurt. Maybe you should try it yourself and get an answer!

Measure the temperature in a room, then get a yogurt from the freezer, leave it in a place close to the thermometer and measure the temperature every 20 to 30 minutes, observing the yogurt until it melts. If the room is too hot it will take less time than if the room is cold.
