Answer 2

Answer:

1.)switches

explanation:

A device designed to open or close a circuit under controlled conditions is called a switch. The terms “open” and “closed” refer to switches as well as entire circuits.

2.)answer:

current

Explanation:

A continuous flow of electricity through a circuit is called current electricity. An unbroken circuit is called a(n) closed circuit .

3.)answer:

kelvin k

explanation:

The kelvin (K) is defined by taking the fixed numerical value of the Boltzmann constant k to be 1.380 649 ×10−23 when expressed in the unit J K−1, which is equal to kg m2 s−2 K−1, where the kilogram, meter and second are defined in terms of h, c and ∆νCs

4.)answer:

temperature

explanation:

The hotness of an object is determined by its temperature.

5.)answer:

solid expand on heating and contract on cooling
