Will heat travel faster through a glass cup or a plastic cup?
It depends on the kind of plastic but mostly (I'd think) plastic is a better insulator for heat transport
Why does a piece of steel heat up more than an equal mass of plastic when both absorb the same heat?
Steel has a heat capacity of about 0.49 kJ/kg/°C. Solid plastics have a heat capacity of about 1.67 kJ/kg/°C. It thus takes more energy to warm plastic 1 °C than to warm steel 1 °C. As to why steel has a higher heat capacity than plastic... It may be because plastics have more ability to absorb energy into the vibrational modes of the atoms in the long polymer chains than steel does in its fairly fixed crystaline/metal structure.
What factor most influence the amount of energy needed to change the temperature of a substance?
specific heat capacity
How does heat capacity makes water a good heat sink?
If a body of water has a high heat capacity, it can store more thermal energy making it a good heat sink.
What is the speciic heat capacity of KNO3?
What is the specific heat capacity of kno3
Which cup can hold heat better a plastic cup a coffee cup or a glass cup?
A glass cup will conduct heat away quickly - a plastic cup would hold heat the best.

Does a polystyrene cup hold more heat than a plastic cup?
Polystyrene
Would a plastic cup keep the water hot longer than a metal cup?
A plastic cup holds more heat because plastic can't take out heat. Glass conducts heat away.
Can plastic cup be replaced by glass beaker in determination of heat of solution?
yes.but plastic cup is a better good insulator than glass beaker.
Will a liquid remaine hot longer in a plastic cup or in a metal cup?
It depends on which one radiates heat fastest. Since plastics are generally poor heat conductors, you'd expect the plastic cup to cool more slowly. But a thin plasic cup, painted black, may radiate more heat than a very shiny metal cup.
Why would a plastic kettle stay hotter than a metel kettle?
How long something stays hot depends on its heat capacity. Heat capacity is a measure of the amount of energy required to change the temperature of an object.Water has a relatively large heat capacity per gram whereas metals have a low heat capacity. This means that water retains it heat but metals heat and cool quickly. We can take a metal tray from an oven and put it to cool, we can touch the tray soon afterwards but the roast that we put on the serving platter stays hot for a lot longer.The plastic in the kettle will cool depending on its heat capacity. Metal cools quickly due to its low heat capacity.
How much does a glass cup hold?
It depends on the size of the cup. What a cup is made of says nothing about its capacity. For instance, a one-cup measuring cup holds one cup, whether it is made of metal, plastic, or glass.
What cup is easier to hold with hot water a plastic one or metal?
a styrofoam cup. i tried it on my science project
What is plastic's specific heat capacity?
There are many different kinds of plastic, so there would be no "fixed" latent heat of vaporization. Additionally, heating most plastics would not cause them to vaporize. They would burn in the presence of air (oxygen), or pyrolize in an inert atmosphere. Plastics won't generally change from a liquid to a gas like water becomes steam when it is hot enough. The heat will cause chemical changes in the plastic, and it will cease to be what it was in the beginning.
