In the winter, a heated home in the Northeast might be maintained at a temperature of 78°F. What is this temperature on the Cels
masya89 [10]

Answer:  25.6^0C,  298.6K

Explanation:

Temperature of the gas is defined as the degree of hotness or coldness of a body. It is expressed in units like ^0C and K  

These units of temperature are inter convertible.

We are given:

Temperature of the gas = 78^0F

Converting this unit of temperature into ^0C by using conversion factor:

^oC=\frac{5}{9}\times (^oF-32)

^0C=\frac{5}{9}\times (78^oF-32)

25.6^0C

Converting this unit of temperature into K by using conversion factor:

K=t^0C+273

K=25.6+273

298.6K

Thus the temperature on the Celsius and Kelvin scales are 25.6^0C  and 298.6K respectively.

Which particle diagram represents a mixture of three substances
Anni [7]

Following the key in the diagram (see the attached image), the only particle diagram that represents a mixture of three substances is diagram 2.

To simplify it, let us replace the key in the diagram as follows;

  1. atom of one element = A
  2. atom of different element = B

Diagram 1 consists of only AA and AB

Diagram 2 consists of AA, BB, and AB.

Diagram 3 consists of AA and ABA

Diagram 4 consists of AA and BAB

Thus, only diagram 2 has a mixture of 3 substances.
