Lab Kinetic Molecular Theory Mixing food colouring into water of different temps

Help me solve this questions 1, 2 and 3.

Consider equal volumes (say 1 L) of a given substance in the solid, liquid, and gas phases. Arrange them in order of decreasing mass based on the trend for the average substance. If the mass difference between samples is relatively small (10% or less), rank the items as equivalent. Rank from greatest to least mass. To rank items as equivalent, overlap them. • View Available Hint(s) Reset Help 1 L of substance in the solid phase 1L of substance in the gas phase 1L of substance in the liquid phase Greatest mass Least mass

Write TRUE if the statement is accurate and FALSE if the statement is flawed._________ 1. A gas consists of a collection of small particles traveling in straight line motion and obeying Newton’s laws. _________ 2. The molecules in a gas occupy negligible volume._________ 3. Collisions between molecules are perfectly elastic (that is, no energy is gained or lost during the collision.) _________ 4. There are negligible, attractive, or repulsive forces between molecules._________ 5. The average kinetic energy of a molecule is constant

Directions: Match Column A to Column B. There can be multiple answers in each number. A a. No definite shape but has definite volume b. Has no capability to flow c. Can change volume easily d. Molecules possess less or no motion. e. Molecules has the most kinetic energy 1. Solid 2. Liquid 3. Gas

1. Why should solid NaOH be weighed on a watch glass and not on a paper?

The particles move in a between collisions. a. straight –line b. curved path 3. The speed of the particles changes following the collision with a. another particle b. the wall of the container c. both the wall of the container and another particle. Use the Track function explained earlier to help answer this question. 4. Collisions between particles or the walls of the container are elastic or not elastic. 5. The particles attractions to other particles. а. еxperience b. do not experience 6. The RMS speed of helium is as the mole of helium changes. a. constant b. variable 7. Record the RMS speeds of different gases in the following table. Table 1. RMS speed of gases Gas Не Ne Ar Molar mass g/mol RMS speed m/s 8.

19. Use the kinetic-molecular theory to explain each observation given. a. Wax melts near the flame of a burning candle. b. Liquid water may be converted into ice cubes in a freezer. c. Ginger ale flows to match the shape of a glass. d. Water gradually evaporates from a swimming pool. e. Water vapor condenses inside house windows on cold days. f. Snow gradually disappears, even when the tem- perature remains below freezing. g. Solids and liquids cannot be compressed as much as gases.

1. What pieces of apparatus or equipment are used for measuring: a. Temperature? b. Small amount of liquids? c. Large amount of liquids? d. Mass of a substance? 2. Suggest ways on how to store and handle properly the different glassware to avoid accidents in the laboratory. You can use illustrations to show your idea. 3. Why is the most of the containers of substances and those used for heating are made up of glass rather than metal? 4. Explain why the thermometer should not be shaken rigorously to lower the reading to zero before using it.

What materials will the teacher and the students need to complete a lesson on mixing substances in a 5th grade classroom based on the below standard and learning objective? Standard Conduct an investigation to determine whether the mixing of two or more  substances results in new substances.  Learning Objective Given a variety of substances and safety equipment in a classroom setting, students will be able to conduct an experiment to mix two or more substances and observe the results. They will be able to correctly identify whether a new substance has been formed as a result of the mixing, based on observable changes such as color change, formation of a precipitate, or change in temperature, with at least 80% accuracy.
