Will the holding time of the thermos cup change according to the weather and temperature?

The holding time of the thermos cup will change according to the weather temperature.

Because the heat of the object in the thermos cup will also radiate outward, but at a slower speed. When the outside temperature is low, the heat will dissipate faster and the heat preservation time will be shorter. So it has something to do with weather and temperature.

Introduction:

A thermos cup is simply a cup that can keep warm. Generally, it is a water container made of ceramic or stainless steel and vacuum layer. The top of the container is covered and sealed tightly. Vacuum insulation layer can delay the heat dissipation of water and other liquids to achieve the purpose of insulation. The thermos cup is developed from the thermos bottle. The principle of heat preservation is the same as that of thermos bottles, except that people make bottles into cups for convenience. There are three ways to spread heat: radiation, convection and transmission. The silver cup liner in the thermos cup can reflect the radiation of hot water, the vacuum between the cup liner and the cup body can block the heat transfer, and the bottle which is not easy to transfer heat can prevent the heat convection.

The thermos cup is refined by advanced vacuumizing technology, with elegant appearance, seamless inner container, good sealing performance and good thermal insulation performance. You can put ice cubes or hot drinks. At the same time, functional innovation and detailed design also make the new thermos cup more connotative and practical.
