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.
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
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 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.
What is it when energy from hot cocoa melts a marshmallow placed in it?
This is convection. Convection is the effect you get when hotter parts expand and have lower density than cooler parts. What you describe is "melting", with the temperature of the surrounding liquid being higher than the temperature of the marshmallow. So, heat flows from the hotter region to the cooler by conduction and eventually the temperature reaches the melting point.I'd suggest re-arranging that.Conduction transfers the cocoa's heat into the marshmallow, cooling the liquid in doing so.Convection helps to maintain the process by replacing the cooled cocoa with hot.When you place any chocolate in any fluid at a higher temperature than the melting point of chocolate, the chocolate will melt. Likea lump of ice in warm water. Convection playsno role at all- if you prevent convection by packing the fluid with small pebbles etc, the marshmellow will still melt. The heat is transferred by conduction, not convection.
When measuring a cup of cocoa powder what do you use?
I use a table spoon.

What are considered chocolates?
If they have a certain amount of cocoa.

How does cold milk cools hot cocoa?
since there is kinetic energy in both hot and cold objects the particle in the hot objects move fast causing heat and the particles in the cold object move slower so the cold kinetic energy can cause the hot kinetic to become cooler in other words When you pour cold milk into hot cocoa the milk and cocoa particles start to collide. When a high-energy cocoa particle hits a low-energy milk particle, energy transfers. The cocoa particles slow down and the cup of cocoa cools down.
How much does unsweetened cocoa cost?
The cost of unsweetened cocoa depends on the amount, brand, and store. In general is can cost $4-$7 a pound for unsweetened cocoa.
Where is cocoa land?
It is in the west of Africa, a meadow that goes on for miles and it is filled with an extremly huge amount of coca and cocoa trees.
What countries produce the largest amount of cocoa beans?
Spain
Why are cocoa beans grown in poor countries?
cocoa beans are grown in poor countries as there are less resources to process them and thre is a huge amount of soil which mostly cocoa beans grow out of?
How much cocoa is in an chocolate sandwich cookie?
The amount of cocoa in a chocolate sandwich cookie varies by recipe. The only way to know for sure how much cocoa in is a specific cookie is to have the recipe.
Explain the direction of heat transfer between a mug of hot cocoa sitting in a cold room and explain what eventually happens to the average kinetic energy of the cocoa as a result of the transfer.?
The heat is going from the hot cocoa outwards into the room, as this is an exothermic thing meaning it puts out heat. The average kinetic energy will be lower than original simply because there is less heat.
