Define thermal and electrical conductivity, solubility, magnetism, melting and boiling points
Anon25 [30]

Answer:

<u>thermal conductivity:</u> the rate at which heat is transferred by conduction through a unit cross-section area of a material, when a temperature gradient exits perpendicular to the area

<u>electrical conductivity:</u> the measure of the amount of electrical current a material can carry or it's ability to carry a current

<u>solubility:</u> the ability to be dissolved, especially in water

<u>magnetism:</u> a physical phenomenon produced by the motion of electric charge, resulting in attractive and repulsive forces between objects

<u>melting point:</u> the temperature at which a given solid will melt.

<u>boiling point:</u> the temperature at which a liquid boils and turns to vapor

If a 250.0 mL sealed plastic bag starts out at a temperature of 19.0 °C and after sitting in the sun reaches a temperature of 60
Marizza181 [45]

Answer:

D

Explanation:

If the pressure remains constant then the temperature and Volume are all that you have to consider.

Givens

T1 = 19oC = 19 + 273 = 292o K

T2 = 60oC = 60 + 273 = 333oK

V1 = 250 mL

V2 = x

Formula

V1/T1 = V2/T2

250/292 = x/333                

Solution.

The solves rather neatly.  Multiplly both sides by 333

250*333 / 292 = 333 *x / 333

Do the multiplication

250 * 333 / 292 = x

83250 / 292 = x

Divide by 292

x = 285.1 mL

The answer is D
