True, but it can get very, very soft if the room is warm.
ice can melt at room temperature. Anything that is liquid at room temperature would, in its frozen state, melt at room temperature. Oils, beverages and mercury - if in a frozen state - would melt when exposed to room temperature.
Butter melts faster than ice because fats in the butter require less energy to move up a degree when compared to ice
it doesnt
so it doesnt melt! DUHHHHH!
So that the ice cream doesnt melt
Yes, butter can be a liquid when it is melted. At room temperature, butter is typically solid. Heating butter to a temperature above 95°F (35°C) will cause it to melt and become a liquid.
increased
because the good lord said let it melt
at normal temperature above zero degree centigrade
Start with butter at room temperature (If it's from the fridge you can microwave for a few seconds, but don't melt it). Beat it with a fork until it is light and fluffy. Add the sugar and beat it until all the sugar is mixed in well.
Yes it can vary in temperature because then it would never melt
To correctly answer this I would need to see the recipe. But many frosting recipes require you to only soften the butter and never to melt it. In order to have a frosting turn out thick the butter needs to be softened. If it's melted it won't properly combine with the other ingredients.
