Chapter 8. Book 3 introduction to thermodynamics.

Question 1

Matter

Answer 1

Matter should be considered to have mass occupies space and physical properties. Enough chemical properties that can exist in three different different states solid liquid or gas, and may be elemental, which is composed of only one element or a compound, which is composed of a number of elements physical properties of matter are density boiling point freezing point and flashpoints chemical properties indicate how old is compound or element unites with other elements or compounds

Question 2

Linear and volumetric expansion of solids

Answer 2

The amount of length increase in linear expansion, depends on material of construction and temperature change when finding linear expansion multiplied the temperature change coefficient of linear expansion for the material, then multiply it by the number of meters to get your final length as the coefficient determines the linear expansion of 1 m and not the entire length when finding volumetric expansion, it is the same formula but the coefficient of linear expansion is multiplied by three to get the coefficient of volumetric expansion

Question 3

Temperature scales

Answer 3

There are four different temperature skills used and they are Fahrenheit, Rankine Celsius, and kelvin 0 kelvin is equal to -273°C and 0°. Rankine is equal to -460°F for each degree gained or lost is the same in Celsius or kelvin so degree Gand and Celsius is equal to the degrees gained in kelvin.

Question 4

Temperature definition

Answer 4

The temperature of a body is a measure of the speed at which the body molecules vibrate heat flows naturally from point of high temperature towards one of low temperature

Question 5

Heat definition

Answer 5

Heat is a measure of the quantity of internal vibration energy in a substance where the temperature is a measure of the intensity or hotness of heat in a body

Question 6

Sensible heat may be added to, or removed from a substance, causing a temperature change, but not a state change, three forms of sensible heat, or sensible heat of the solid sensible heat of the liquid, sensible heat of the gas/vapor,

Answer 6

Sensible heat

Question 7

Latent heat

Answer 7

Latent heat can be added or removed to cause a stage change. It does not cause a temperature change for terms used for latent heat are related to heat of fusion which is solid to liquid change during the addition of heat.-latent heat of evaporation, which is liquid to vapor during the addition of heat-latent heat of condensation, which is the change of vapor to liquid by removing latent-and let it heat of solidification, which is liquid to solid by removing latent heat
