How is energy transferred when an instant cold pack is put on muscle injury?
Heat energy is transferred by conduction from the muscle to the cold pack.
How is heat transferred when a person holds a ice pack?
Heat will travel from the person's hand into the ice pack, where it will excite the molecules there and warm the ice pack.
What takes place as an ice cube cools a drink?
kinetic energy in the drink increasesA calorie of heat energy is transferred from the ice to the water of the drink. Because ice absorbs heat from the drink, cooling down its temp.Common mistake:People think that ice producess coldness, when all its doing to the drink is absorbing the heat, causing the ice cube to melt ;)You say that a calorie of heat energy is transferred from the ice to the water, but that is not entirely correct as a calorie is defined as the amount of heat that 1g of water releases when it cools by 1 degrees Celsius. What if i add a really small block of ice? Surely a calorie of heat will not be transferred from the ice to the water. Therefore it would be more correct to say that the total kinetic energy of the drink decreases.
When ice on a plate melts why does the plate cool down as well?
When ice is placed on a plate that is warmer than the ice, some of the heat energy from the plate is transferred to the ice. (This is due to the molecules in the plate transferring kinetic energy to those in the ice. The molecules in the plate crash into those in the ice, losing speed and giving the molecules in the ice more speed). Since the heat energy is transferred away from the plate, the plate cools down. (The ice is not cooling down, it is heating up.)
Energy transferred by waves or rays?
Yes, energy can be transferred that way.

Is cold pack exothermic or endothermic?
Endothermic- a change in which energy is taken in. The melting of ice is an endothermic change. Ice absorbs thermal energy from its surroundings when it melts. That's why you pack drinks and food in an ice-filled picnic cooler to keep them cold. So yes an ice cube is endothermic.

What is transferred from organism to organism in a food chain?
energy is transferred from on animal to the other animal. Because energy can't be destroyed only transferred
How is wind energy transferred?
Wind energy is transferred by wind mills.
What is the rate at which the energy is transferred?
The rate at which energy is transferred is called POWER
Energy transferred by waves or rays?
Yes, energy can be transferred that way.
How is energy transferred into an inclined plane?
Energy is transferred into an inclined by effort
