A double-walled insulated stainless steel cup will keep water hot for the longest period of time, typically up to 6-12 hours. It is designed to reduce heat loss through its layers, providing better insulation compared to regular cups. Vacuum-sealed bottles or cups are also good options for keeping liquids hot for extended periods.

What type of cup keeps hot water hot the longest?

A double-walled insulated cup made of stainless steel or ceramic will keep hot water hot the longest due to its ability to retain heat and prevent heat loss. Vacuum-sealed tumblers are also effective in maintaining the temperature of hot drinks for an extended period of time.


If i use a thermometer what will be the temperature in the plastic cup with hot water?

That depends on how hot the water is in the cup. Use the thermometer to measure it and see.


How are the water molecules positioned in the hot cup?

In a hot cup of water, the water molecules have higher kinetic energy and are moving faster than in a cold cup. This results in the water molecules being more spread out and having increased motion, leading to a less structured arrangement compared to cold water.


Why does water not form on the outside of a cup when you have a hot drink?

Water does not form on the outside of a cup when you have a hot drink because the heat from the drink is transferred to the cup and prevents the air surrounding the cup from reaching its dew point and forming condensation. This is because the cup acts as a barrier, keeping the outer surface temperature above the dew point.


Which molecules will move faster water molecules in a cup of hot soup or water molecules in a glass of iced lemonade?

Water molecules in a cup of hot soup will move faster than water molecules in a glass of iced lemonade. The higher temperature of the hot soup provides more energy to the water molecules, causing them to move faster.
