Which of the following apply to temperature and the kelvin scale. Select all that apply. 0 K is equal to -273 degrees Celsius. T

he term “degree” is not used with the Kelvin scale. Cryogenics is the study of very low temperatures and their effects. Gas can have a volume of 0. Scientists have been able to cool substance to absolute zero.

<h2>Answer:</h2>

The statement number 1 ,2, and 3 apply to the temperature and kelvin scale.

<h3>Explanation:</h3>

Statement 1: The first statement which is that 0 K is equal to -273C is the correct statement and it can be applied to temperature and kelvin scale.

                                               K = C + 273

                                               0 K = (-273C ) + 273

Hence proved 0 k is equal to -273 C.

Statement 2: The term degree is not used with kelvin scale. Yes it is a correct statement because it is used with Celsius degree(temperature unit).

Statement 3: This statement is also correct. Cryogenic is the study of freezing temperature and its effects on objects like on some organs.

Statement 1: 0 K = -273 °C. This is true. This has come to be  referred to as absolute zero which is very theoretical as it has never been attained.

Statement 2: °C is not used with Kelvin scale. This is true. Kelvin is a scale equivalent to °C and thus ° is not used with Kelvin scale and this would be a different scale all together which does not exist.

Statement 3: Cryogenics has been defined as the production and characteristics of materials at very low temperatures. Therefore, it can also be defined as a study and thus this statement is true.

Statement 4: Volume of gas at absolute zero is, theoretically, thought to be zero. This is due to the reasoning that at that temperature, all the gas will have condensed to liquid. However, absolute zero temperature has never been attained. Therefore, this statement is  theoretically true.

Statement 5: Scientist have not yet cooled anything to absolute zero and thus this  statement is false.

What's the minimum Out PUT WORK<br> required to raise 14,0m3 of water 26.0m?
BartSMP [9]

Answer:

3.57 MJ

Explanation:

ASSUMING it's fresh water with density of 1000 kg/m³

W = ΔPE = mgΔh = 14.0(1000)(9.81)(26.0) = 3,570,840 J

Salt water would require more.

A sewing machine uses 1.6kWh of electricity in one day. If electricity costs 9p per unit, what is the total cost in pence of usi
atroni [7]

Answer:

\huge\boxed{\sf 1.6\ units = 14.4p}

Explanation:

Since,

<h3><u>1 kWh = 1 unit</u></h3>

So,

1.6 kWh = 1.6 units

If,

<h3>1 unit = 9p</h3>

1.6 units = 9p × 1.6

1.6 units = 14.4p

PLEASE HURRY 20 PTS
Crank

Answer:

A. The electric field points to the left because the force on a negative charge is opposite to the direction of the field.

Explanation:

The electric force exerted on a charge by an electric field is given by:

where

F is the force

q is the charge

E is the electric field

We see that if the charge is negative, q contains a negative sign, so the force F and the electric field E will have opposite signs (which means they have opposite directions). This is due to the fact that the direction of the lines of an electric field shows the direction of the electric force experienced by a positive charge in that electric field: therefore, a negative charge will experience a force into opposite direction.
