What occurs when a 35-gram aluminum cube at 100C is placed in 90 grams of water at 25C in an insulated cup?
Heat if transferred from the aluminum to the water, and the temperature of the water increase
Will a metal cup or a styrofoam cup keep the hot water warm after a short time?
It is the Styrofoam cup as it is not a good conductor of heat but the metal cup is a good conductor of heat.
It is a cold night around the campfire. Megan is trying to get warm by sitting close to the fire and clutching her mug of hot chocolate. How is heat being transferred to chilly Megan?
From the fire the transfer is by radiation. From the coffee cup to Megan's hands the transfer is by conduction
Why do you use a foam cup instead of a beaker in an experiment?
foam cup is a poor conductor of heat! haha;] msg me!!
Does Styrofoam cups keep hot drinks hot or cold drinks cold?
A Styrofoam cup will do both. The Styrofoam is an insulator, and, as such, it slows the transfer of heat between the system (the drink) and the surroundings (everything outside the cup) If it is a cold drink, heat moves very slowly through the cup toward the drink. If it is a hot drink, heat moves very slowly through the cup toward the surrounding air.
What is called when you pick up a hot cup and the heat is transferred to your hand?
This is conduction
What if A woman picks up a cup of hot cocoa and feels her hands get warmer. What statement best explains what is happening?
That means that heat energy is transferred from the hot cup, to the hands.
How is heat energy transfed from the cocoa to the spoon?
Assuming you have a cup of hot cocoa, then the heat transfer is by conduction
What are 2 energy conversions that takes place when you warm up a cup of cocoa in a microwave oven?
An energy conversion that takes place when you warm a cup of hot cocoa in a microwave is a transfer of heat from the microwave's microwaves to the hot cocoa.
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.
When a cup of tea cools down how is the heat transferred to the surroundings?
?????
Where does the heat go from a cup of hot cocoa sitting on the table?
Hot air rises.
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
When you pick up a hot cupheat is transferred from the cup to your hand primarily by?
it is the conduction
How many milliliters in a cup of cocoa?
240 ml in a cup of cocoa
Why an object losses heat?
An object loses heat because all warmth flows into colder objects. For example, if you are holding a cup of hot cocoa on a cold winter day the heat of the cocoa will go into your cold hands. This is an example of thermal energy.
How is heat transferred when a cup of hot coffee is placed in a freezer?
Heat can beradiated,conducted or travel byconvection or a combination of these three.The base of the cup would conduct the heat to the surface it is sitting on and the body of the cup would radiate the heat and the air in the freezer would transfer the heat by convection currents.
