Two objects are made of the same material, but they have different masses and temperatures.

Part A

If the objects are brought into thermal contact, which one will have the greater temperature change?

a. The one with the lesser mass.
b. The one with the lower initial temperature.
c. The one with the higher initial temperature.
d. The one with the higher specific heat.
e. The one with the greater mass.
f. Not enough information

a. The one with the lesser mass.

Explanation:

Since , both are made of the same material , they will have same specific heat . On physical contact , heat will be exchanged between them with heat flowing from body at higher temperature to one at lower temperature . Amount of heat lost by one will be equal to amount of heat gained .

So temperature change will take place in both of them  but they will not be same . Body of higher mass will undergo lesser change in temperature because of the following relation

Q = mcΔT

ΔT = Q / mc

ΔT   ∝   1 / m

change in temperature will be inversely proportional to mass of object if Q or heat exchanged is constant .

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:

so here is the information for current research:

-nrel's geothermal analysts, scientists, and engineers perform a full range of research from developing advanced methods of locating and accessing geothermal resources to exploring innovative technologies to extract and produce clean energy from the heat of the earth

and here is the information for the technology of geothermal energy:

-it's clean and sustainable

-resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma

-almost everywhere, the shallow ground or upper 10 feet of the earth's surface maintains a nearly constant temperature between 50° and 60°f (10° and 16°c)

-geothermal heat pumps can tap into this resource to heat and cool buildings

-a geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building

-in the winter, the heat pump removes heat from the heat exchanger and pumps it into the indoor air delivery system

-in the summer, the process is reversed, and the heat pump moves heat from the indoor air into the heat exchanger

-the heat removed from the indoor air during the summer can also be used to provide a free source of hot water
