All material substances, including plastics of every type, can absorb heat to a greater or lesser degree (the measurement of heat absorbing ability is officially known as heat capacity). There are plastics that will melt if you heat them, but they still absorb heat, even as they melt.

Name two plastic groups related to heat and moulding plastics?
Two common plastic groups used for heat and moulding plastics are thermoplastics, which can be melted and remoulded multiple times through heating and cooling processes, and thermosetting plastics, which undergo a chemical change during moulding and cannot be remelted or reshaped after the initial moulding process.
Is silver endothermic?
Silver is not endothermic. Endothermic reactions absorb heat from their surroundings, while silver does not have a natural tendency to do so. Silver is a good conductor of heat, meaning it can transfer heat easily but does not absorb heat in an endothermic process.
Does plastic absorb chemicals?
Yes, plastic can absorb and release chemicals, especially in the presence of heat or acidic substances. This can be a concern as chemicals from the plastic may leach into food or liquids stored in plastic containers. Using food-grade or BPA-free plastics can help reduce the risk of chemical absorption.
Do clear liquids absorb heat?
Clear liquids, like water, have the ability to absorb and retain heat. When exposed to heat, clear liquids will increase in temperature as they absorb the thermal energy. This property is utilized in various applications such as cooling systems and heat transfer processes.
What is the water content of plastic?
The water content of most plastics is negligible as they are typically hydrophobic and do not readily absorb water. However, some plastics can absorb trace amounts of water over time through a process known as water absorption or moisture uptake. This can impact the properties and performance of the plastic material.
What colors cannot absorb heat?
No color is impervious to heat.
What substances do not absorb in the microwaves?
Glass, ceramics, and most plastics do not absorb microwaves, so they do not heat up in the microwave. Metal, however, reflects microwaves, which can lead to sparking and potentially damage the microwave.
Do saucepans have plastic handles because plastics are good conductors of heat?
No, saucepans have plastic handles because the plastic doesnt absorb as much heat as the metal, making you able to pick up the pan without burning yourself
What is the definition of Thermosetting plastics?
Plastics which once moulded into a shape do not become soft on heating and cannot be moulded again are called thermosetting plastics.
Name two plastic groups related to heat and moulding plastics?
Two common plastic groups used for heat and moulding plastics are thermoplastics, which can be melted and remoulded multiple times through heating and cooling processes, and thermosetting plastics, which undergo a chemical change during moulding and cannot be remelted or reshaped after the initial moulding process.
Why do some objects absorb more heat than others?
Objects absorb heat differently based on their material composition. Materials with higher thermal conductivity, such as metals, absorb heat more easily compared to materials with lower thermal conductivity, such as wood or plastics. Additionally, factors like color and surface texture can affect how much heat is absorbed by an object.
Do black objects absorb heat?
They absorb light which is converted into heat energy
Can a sponge absorb heat?
A sponge definitely does have the ability to absorb heat. Sponges absorb heat as well as many other things like water.
Do flowers absorb heat?
Flowers do not absorb heat directly as they do not have the metabolic processes to generate heat. However, they can be affected by heat from their surroundings, which can impact their growth and development.
If someone were talking about thermally conductive plastics what would they be referring to?
Thermally conductive plastics are plastics which heat up because they conduct heat due to their chemical composition. These types of plastics are available from the Premix Group, Masterbond and T Global Thermal.
Is fibreglass a thermal insulator?
Yes, because it does not easily absorb heat, so it cannot carry it from one point to another.
Is silver endothermic?
Silver is not endothermic. Endothermic reactions absorb heat from their surroundings, while silver does not have a natural tendency to do so. Silver is a good conductor of heat, meaning it can transfer heat easily but does not absorb heat in an endothermic process.
