It is found that the bulb of the tester glows bright for liquid A‚ while it glows very dimly for liquid B. We can conclude that liquid A is a better conductor than liquid B. A) True B) False View Solution Question 5 Tremors on the earth can also be caused when a volcano erupts‚ or a meteor hits the earth‚ or an underground

measure volume‚ mass‚ density‚ and specific gravity of solids and liquids with accuracy. Equipment: Students use the electronic balance to measure the mass of metals‚ pipettes‚ and pipettes holding liquids. The user presses the tare button to set the scale back to 0 g‚ and then places the metal or pipette onto the balance. The result is rounded to two decimal places. The graduated cylinder is used for measuring volume of a liquid or water displaced by a solid. The students look at lines‚ at eye

Kinetic energy is increasing between letters A-B‚ C-D and E-F. Based off the observations‚ in phase A-B Tert-Butyl Alcohol stays a solid‚ in phase C-D Tert-Butyl Alcohol stays a liquid‚ and in phase E-F the chemical stays a gas. This is observed at the particle level because temperature is a measure of Ek; the temperature is increasing which increases kinetic energy. Since Ek is the energy of motion‚ the particles would increase their velocity and the number and force of collisions. However‚ the

What two phase changes occur between vapor water and liquid water‚ and at what temperature does each phase change take place? Essay 8. Use billiard balls to model the motion of particles in a gas. Use students in a crowded hallway to model the motion of particles in a liquid. Use an audience in a movie theater to model the motion of particles in a solid. Other USING

The differences in the characteristics of states of matter are given in the following table. S. No. | Solid state | Liquid state | Gaseous state | 1. | Definite shape and volume. | No definite shape. Liquids attain the shape of the vessel in which they are kept. | Gases have neither a definite shape nor a definite volume. | 2. | Incompressible | Compressible to a small extent. | Highly compressible | 3. | There is little space between the particles of a solid. | These particles have a greater

muslin. Liquid: Put 1 cm3 of the liquid food sample into test tubes. -grease spot test: A drop of liquid food sample was added to a filter paper and was let to dry for 5 minutes. The filter paper was held up to the light and any translucent spot was observed. The filter paper was put into an organic solvent. it was taken out and let to dry The filter paper was examine against light again. (positive result – translucent spot disappears) -Clinistix paper: A drop of liquid food

Relating Mass and Volume Question: What does mass have to do with the amount of space (volume) a liquid occupies? Hypothesis: I believe that the mass and volume is related because they both rely on each other for their purpose. If we fill the cylinder to a certain measurement (volume)‚ then the mass will grow with it. There is a balance. Materials: - Distilled water - Corn syrup - Saturated solution of salt water - Triple beam balance - 150 mL (or larger - Small plastic pipette - 150 mL beaker

in solids‚ liquids‚ gases‚ and plasmas. You can determine whether an object is a solid or not based on two characteristics. Solids have a definite shape and a definite volume. Solid’s particles are so close together that they cant move and that’s what keeps a solid a definite shape. Little motion can occur in the particle arrangement. Particles in liquids‚ however‚ can move more freely. The particles are close together but are not as tightly packed as solids are. Like solids‚ liquids have no definite

Objective: The purpose of experiment of density determination is to determine the densities of regularly shaped object and irregular shaped solids as well liquids. Density equal mass over volume. Materials Used: Materials used in this experiment was a regular shaped object and irregular shaped object and a ruler to take the measurements of the object. A graduated cylinder and electric beam balance were used to measure the volumes and masses of the object. As well 5-20% concentrated were
