PEX pipe will keep it hot longer than copper.
polystyrene
use insulation to keep the water hot for 40 minutes
keep it in a hot place
A styrofoam cup can help to retain heat, but it is not as effective as materials like ceramic or insulated metal. Hot water in a styrofoam cup will cool down faster compared to using a better insulated material.
Materials with good thermal insulation properties, such as vacuum insulated stainless steel or double-walled glass, can keep water hot for longer periods by minimizing heat transfer with the surroundings. Additionally, materials with high heat capacity, like ceramics or food-grade plastics, can help retain heat for a relatively longer time. Proper sealing of the container can also contribute to maintaining water temperature.
No, It doesn't. If you want to keep hot water hot for a longer time use a polystirene cup.
The materials needed for the experiment are: two containers to hold the water, hot water, cold water, thermometers to measure the temperature, a freezer to freeze the water, and a timer to record the time it takes for each to freeze.
Materials with low thermal conductivity such as foam, fiberglass, or double-walled stainless steel are good insulators to keep water hot. Ensuring a thick layer of insulation around the water container or using a vacuum-sealed flask can also help maintain the water temperature for longer periods.
thaw it under the sink with hot water. then keep it in a bucket of hot water
try covering the glass, so the heat particles stay inside the cup, and the hot water stays hot.
To keep the water hot longer. Saves on heating costs.
Hot water works just keep rubbing hot water and soap it happend to me
