A polystyrene cup feels warm because it is a poor conductor of heat. This means that heat is not transferred easily from the outside of the cup to the inside and the cup is unable to dissipate the heat quickly. Instead the heat generated by the liquid inside the cup is trapped making the cup feel warm to the touch.
The material of a polystyrene cup is designed to insulate meaning it does not easily transfer heat. This means that heat generated by the liquid inside the cup is retained causing the cup to feel warm to the touch. Other materials such as metal or ceramic are much better conductors of heat and are better able to dissipate heat quickly.
The following characteristics of polystyrene make it a poor conductor of heat:
- Low thermal conductivity
- High resistance to heat transfer
- Low thermal diffusivity
When a polystyrene cup is filled with a hot liquid the heat of the liquid is not easily transferred out of the cup making it feel warm to the touch. This is why polystyrene cups are often used for hot beverages.
What else can I help you with?
Which object has more thermal energy: a cup of hot coffee or a bowl of warm soup?
The cup of hot coffee has more thermal energy than the bowl of warm soup.
Which way would thermal energy flow if you hold a cup with hot drink?
Thermal energy would flow from the hot drink to your hand, as heat always moves from a warmer object to a cooler one. Thus, the cup's heat would transfer to your hand, making it feel warm.
What kind of heat transfer is you feel the warm glow of a bonfire?
You feel the warm glow of a bonfire through the process of heat transfer known as radiation. The heat energy from the fire is emitted in the form of electromagnetic waves, which travel through the air and reach your skin, making you feel warm.
Why do you feel warm in direct sunlight but in the shade you feel cooler?
In direct sunlight, you feel warm because the sun's rays heat up your skin. In the shade, you feel cooler because you are not directly exposed to the sun's rays, so there is less heat reaching your skin.
What heat transfer is when you feel warm glow of a bonfire?
The heat transfer you feel from a bonfire is primarily radiant heat transfer. This is when heat energy is transferred through electromagnetic waves from the hot flames to your body, causing you to feel warm.
Why do your hands get warm when you have a hot cocoa in your hand?
Because the warm hot chocolate warms the cup and the cup warms your hands. also if you put your hands over the cup and feel the steam that will warm your hands.
Why your hands feel warm when you hold a cup of hot cocoaa?
When you hold a cup of hot cocoa, your hands absorb the heat from the warm liquid through the cup. This increases the temperature of your hands, making them feel warm. Heat transfer occurs from the hot cocoa to your hands until they reach thermal equilibrium, balancing out the temperature difference.
A hot cup of coffee loses heat faster than a warm cup Why doesnt the hot cup reach room temperature before the warm cup?
The hot cup loses heat faster, but only until it becomes a warm cup itself. Then it loses heat as the warm cup did at the beginning. However, by this point, the hot cup is warm, but the warm cup is now cooler too. Therefore, the warm cup will still become room temperature first.
How do you hold breasts?
