The paper cup starts hotter than the plastic mug, but cools faster than the mug. This is most likely because the mug is bulkier than the paper, so immediately after the hot water is poured into the mug, a lot of the heat is transferred into heating the mug to the temperature of the water.
What retains heat the longest?
Researchers have discovered that tantalum carbide and hafnium carbide materials can withstand scorching temperatures of nearly 4000 degrees Celsius.
Which keeps coffee hotter porcelain or ceramic?
Stoneware mugs tend to keep coffee hot longer than porcelain and china mugs. Not because the material itself is more insulating but rather because stoneware is thicker than porcelain. It is the thickness that keeps the coffee hot longer.
Is an Ember Mug worth it?

Can you microwave a Yeti?
The short answer is no; microwaving a Yeti is not safe. Yeti drinkware, including mugs, tumblers, jugs, and bottles, is made from high-quality 18/8 stainless steel. Steel, like aluminum or any other conductive metal, does not mix well with radiation emitted by microwaves.

Why metal cup is warmer than ceramic cup?
The three methods of heat transfer: conduction, convection and radiation. The steel mug has the highest thermal conductivity of the three materials proposed, 14.3 W/mK. The thermal conductivity of a ceramic mug is approximately 3.8 W/mK, while the thermal conductivity of the glass mug is approximately 1.1 W/mK.
Why does metal cool quicker than ceramic?
Glass, porcelain and plastic will all radiate a similar amount for a given temperature. Steel will radiate rather less, but this is offset by the fact that the high conductivity and low specific heat means that the surface temperature will get hotter much more quickly.
What material stays cold longest?

What liquid absorbs heat?
Water is able to absorb heat – without increasing much in temperature – better than many substances. This is because for water to increase in temperature, water molecules must be made to move faster within the water; this requires breaking hydrogen bonds, and the breaking of hydrogen bonds absorbs heat.
What rock holds the most heat?
Which Stones Absorb the Most Heat? Basalt rocks. For common natural materials, the stones with the highest energy density (from high to low) are gypsum, soapstone, basalt, marble, limestone, sandstone and granite.
