Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.

Please answer only the numbers 1, 4, 7, 10, 13, 16, 17.
Step 2: Identify the dimensions of the quantities involved The second step is to identify the dimensions of the quantities involved in the problem. For example, if the problem involves distance, time, and velocity, the dimensions of these quantities would be length, time, and length/time, respectively. Step 3: Check if the units cancel out The third step is to check if the units cancel out. To do this, multiply the quantities together and check if the units cancel out, leaving only the desired unit. For example, if you are trying to find the velocity of an object and you know its distance and time, you can multiply distance by time to get velocity. If the units cancel out, you have a physically meaningful result. Step 4: Check if the result makes sense, to do this compare the units of the result with what you would expect based on the Robles statement. Using the step hints above, answer the question. You do not have to solve. Just imagine that you're teaching a friend how…
