A family has a furnace that uses natural gas to heat their home. They are moving to an area that offers the option of using energy from a solar power plant to heat their home. Which disadvantage will the family most likely face by making this switch?

a less reliable production of heat

higher costs for the monthly heating bill

an increase in waste production

smaller quantities of heat

Answers

A less reliable production of heat. If they choose to go solar, their house would have to have plenty on sunlight through the day, and they should not live somewhere that gets snow or is cloudy the whole day because it would block the amount of sun the house could get. They would have to plan ahead to figure out if they could use solar or not based on their home and property.

Answer:

A. a less reliable production of heat

Explanation:

Conduction is the transfer of heat between substances with different temperatures. Heat moves from the warmer to the cooler substance through direct contact.

Which feature forms as a result of conduction between magma and water?

di ke
hot spring
caldera
batholith

Answers

Answer:

hot spring

Explanation:

im not entirely sure tbh

Hot springs are formed as a results of conduction of heat between the magma and water. Thus, the correct option is B.


What is Heat conduction?

Heat conduction is the transfer of the internal thermal energy of a system by the collisions of microscopic particles and movement of electrons within a body. The microscopic particles of the body in this heat conduction can be molecules, atoms, and even electrons. Internal energy includes the kinematic and potential energy of the microscopic particles of an object.

Hot springs are formed when the rainwater or the groundwater heats upon by coming in contact with the rocks which have been heated up by the magma, deep beneath the Earth's surface, Hot Spring is formed. This form of geothermal spring generally occurs in the areas near volcanic activities on the planet.

Therefore, the correct option is B.
