Yes it will .
A plastic cup will not keep hot water warm for a significant amount of time. It is not an effective insulator and heat will dissipate quickly. It is recommended to use a thermal mug or a container specifically designed to keep beverages warm for longer periods.
A paper cup typically does not keep water hotter than a plastic cup. Paper is a poor insulator compared to plastic, so heat is more likely to escape from a paper cup, leading to faster cooling of the water inside.
metal cup because it has insulation
No, a galss cup does not keep any drink warm long.
The duration a plastic cup can keep a hot drink warm depends on various factors such as the initial temperature of the drink, the ambient temperature, and the thickness of the cup. Generally, a plastic cup can keep a hot drink warm for about 15-30 minutes. However, using an insulated cup or adding a sleeve can significantly extend the duration by reducing heat loss through conduction and convection.
A plastic cup may help insulate cold water for a short period of time, but it is not as effective as an insulated container. The thickness of the plastic and the ambient temperature will also affect how long the water stays cold.
A glass cup would keep water warm the longest because glass is a good insulator and retains heat well compared to plastic, paper, or styrofoam which are poorer insulators. This is because glass has a lower thermal conductivity compared to the other materials, so heat escapes more slowly.
no it do not keep it longer
If a cup of water is sealed inside a plastic bag and left overnight in a warm area, the heat will cause some of the water to evaporate. The water vapor will then condense on the inner surfaces of the plastic bag, creating droplets. Eventually, you may observe moisture accumulating inside the bag, but the overall amount of liquid water in the cup will remain largely unchanged since the bag is sealed.
Close the system and insulate this very well. That or make the surroundings as hot as the cup.
Just keep a cup (plastic, or a spare coffee cup) on the bathroom sink, fill it with your water, then shut off the water.
Plastic cups are not good at retaining heat, so they do not keep drinks warm for very long. Generally, drinks in plastic cups will start to cool down quickly after being poured. It is advisable to use insulating materials like paper cups or thermal mugs if you want to keep a drink warm for an extended period.
