C) change to water at the same temperature
Explanation:
Adding 334Joules of heat to one gram of ice at STP will cause ice to change to water at the same temperature.
- The heat of fusion is the amount of energy needed to melt a given mass of a solid
- It is also conversely the amount of energy removed from a substance to freeze it.
- The addition of this energy does not cause a decrease or increase in temperature.
- Only a phase change occurs.

Explanation:
The observation of student was that thermometer reading changed from 27°C to 35°C which indicates that temperature of the beaker solution rose after reaction due to release of heat during reaction as a product.
Those chemical reactions which gives heat energy as a product into their surrounding are categorized as exothermic reactions. During the course of these reaction temperature of the surroundings also increased.
So, this means that reaction between silver nitrate and copper wire is an exothermic reaction.
Three ways that the student could speed up the reaction :
- By adding catalyst to the reaction.
- By decreasing the temperature.
- By increasing the concentration of silver nitarte solution.
Your answer would be (D), Noble Gases, or Inert Gases - The far right on the periodic table is also known as Group(0)., or Group 18 on the periodic table. Elements in this group includes, Neon(NE), Argon(AR), Krypton(KR), Xenon(XE), and Radon(RN).
Hope that helps!!!
Convection
Explanation:
Heat is a form of thermal energy borne as result of thermal energy. It is observed as temperature differences between places.
There are different types of heat transfer:
- Conduction
- Convection
- Radiation
Conduction is a heat transfer which involves the actual movement of the collision of the molecules of the medium.
Convection is a heat transfer in fluids by their movement from areas of higher to places of lower heat.
Radiation is heat transfer using electromagnetism and does not involve molecules of the medium
The process of heat transfer from ground to the air touching it is convection. It involves particles of the air.
