Heat is transferred from the cup to your hand through conduction. The molecules in the cup collide with the molecules in your hand, transferring kinetic energy and heat. Additionally, some heat may also be transferred through convection as warmer air around the cup rises and comes into contact with your hand.

What changes in matter when you make a warm cup of coca?
When you make a warm cup of cocoa, the cocoa powder dissolves in the hot liquid, allowing the molecules of cocoa and sugar to spread out evenly throughout the liquid. This increases the overall temperature of the cocoa mixture as heat is transferred from the hot liquid to the cocoa particles, providing a comforting and delicious drink.
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.
What happens to the heat stored in the metal when the metal is poured into the Styrofoam cup of water?
When the metal is poured into the Styrofoam cup of water, the heat stored in the metal is transferred to the water and the cup. This transfer of heat causes the temperature of the water and the cup to increase, as the metal cools down.
Which can transfer more heat a cup of boiling water or 1 basin of tap water?
A cup of boiling water since it has higher temperature. Note that heat transfer depends more on the temperature.
What occurs when a 35-gram aluminum cube at 100C is placed in 90 grams of water at 25C in an insulated cup?
The aluminum cube will lose heat as it cools down to the final temperature of the system. This heat will be transferred to the water causing it to increase in temperature. The final equilibrium temperature will be somewhere between the initial temperatures of the aluminum and water.
What is called when you pick up a hot cup and the heat is transferred to your hand?
This process is called thermal conduction, where heat is transferred from the hot cup to your hand through direct contact.
How is heat energy transfed from the cocoa to the spoon?
Heat energy is transferred from the cocoa to the spoon through conduction. As the cocoa is hotter than the spoon, the heat energy moves from the cocoa to the spoon as the particles in the cocoa collide with the particles in the spoon, transferring kinetic energy.
What if A woman picks up a cup of hot cocoa and feels her hands get warmer. What statement best explains what is happening?
The woman is feeling her hands getting warmer due to the transfer of heat energy from the hot cocoa to her hands. This transfer of heat occurs because of the temperature difference between the hot cocoa and her hands, resulting in her hands absorbing the heat from the cocoa.
When you feel the heat from a hot cup is that conduction?
Yes, feeling the heat from a hot cup is an example of conduction. Heat is transferred through direct contact between the hot cup and your hand.
What changes in matter when you make a warm cup of coca?
When you make a warm cup of cocoa, the cocoa powder dissolves in the hot liquid, allowing the molecules of cocoa and sugar to spread out evenly throughout the liquid. This increases the overall temperature of the cocoa mixture as heat is transferred from the hot liquid to the cocoa particles, providing a comforting and delicious drink.
When you pick up a hot cupheat is transferred from the cup to your hand primarily by?
Conduction. Heat is transferred through direct contact between the hot cup and your hand, causing molecules to vibrate and pass on energy to your skin, resulting in the sensation of warmth.
Is a cup of hot tea a radiation or a conduction or a convection?
A cup of hot tea transferring heat to your hand when you hold it is an example of conduction, where heat is transferred through direct contact between objects.
Is a cup of cocoa thermal energy?
changes from heat energy to mechanical energy because the heat from the hot cocoa is heat energy and mechanical energy is when you move your hand to get the cup or when u drink the hot cocoa
What are 2 energy conversions that takes place when you warm up a cup of cocoa in a microwave oven?
When you warm up a cup of cocoa in a microwave oven, electrical energy is converted to electromagnetic radiation (microwaves) to heat up the water molecules in the cocoa. The absorbed radiation energy is then converted to thermal energy, raising the temperature of the cocoa.
What are two examples of conduction we use every day?
Holding a hot cup of coffee and feeling the heat transfer from the cup to your hand. Using a heated stove to cook food, where heat is transferred from the stove to the pot and then to the food.
When Javier touches a hot mug of tea energy is transferred from the surface of the mug to his hand. What kind of energy is this?
The transfer of heat from cup to hand is known as conduction.
Where does the heat go from a cup of hot cocoa sitting on the table?
Hot air rises.
