Pedro picked up and held a cube of ice in his hand and noticed that he no longer felt a difference in temperature after the ice cube melted in his hand. Which of the following statement best explains what happened? 1.Heat was transferred from Pedro’s hand to the ice increasing the temperature of the ice.
2.Heat was released from the ice cube into the air increasing the temperature of the ice.
3.Cold was transferred to Pedro’s hand from the ice increasing the temperature of the ice.
4.Heat was released from Pedro’s hand into the air melting the ice increasing the temperature of the ice.

the answers is 1.

Explanation:

this is because heat always travel's from the warmest object to the coldest. His hands thermal energy is transferred to the ice making the ice round to the same temperature of his hand. This can also be an example of equalibrum.

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

explanation:

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
