LAB Density, Specific Gravity, Temperature, Specific Heat

Question 1

Density of Liquid

Answer 1

• the certain volume is poured into the container

* the mass of a liquid is measured by (mass of container with liquid) - (mass of container)

Question 2

Density

Answer 2

• every substance has a unique density

- g/mL or g/cm3

Question 3

Density

formula

Answer 3

D=mass(g)/volume(mL or cm3)

Question 4

Specific Gravity

Answer 4

compares the density of a sample to the density of water (1.00 g/mL)

• equates to density of a substance
• used for urine analysis

Question 5

Specific Gravity

formula

Answer 5

Specific = D of sample(g/mL)/ 1.0(g/mL)

gravity

Question 6

Volume Displacement

Answer 6

when a solid is submerged in a known amount of water

final water vol - initial water vol = vol of solid

Question 7

Specific Heat

Answer 7

the amount of heat in calories or joules that raises the temperature of 1 gram of a substance by 1 degree celcius

Question 8

cal to Cal

Answer 8

1000 cal = 1 Cal

Question 9

cal to kcal

Answer 9

1000 cal = 1 kcal

Question 10
