here,
Specific gravity, also called relative density, is the ratio of the density of a substance to the density of a reference substance
the reference substance is water
so, when the specific gravity is greater than one
the density of substance is greater
and the object will Sink
when the specific gravity is less than one
the density of substance is less than water
and the object will Float
can you tell if a substance will float or sink if you know only it’s specific...
A student once noted, “This ratio stuff is great. It’s unbelievable how ratios can tell the complete story behind the problems of a business.” Comment on the student’s observation.
Based on the optical rotation or specific rotation, how can you tell if the (R)-enantiomer is in excess as opposed to the (S)-enantiomer being in excess?
Some people believe the financial statements can tell you all you need to know about a company, while other people believe the character of the management team can tell you all you need to know. Which do you believe is the most important if you were looking at working for the company or investing in the company? You must use material from a reliable source to defend your point of view and site your sources in your post. Your responses...
You heat up a substance with larger specific heat capacity. Compared with a substance with a lower specific heat capacity, will its temperature rise
1. Physics: How does an aircraft carrier that has an average weight of 102,000 tons float on the ocean? Explain your answer. 2. Chemistry: Why does solid water in the form of ice float on liquid water? Explain your answer. * 3. Integrated: A fresh egg sinks in freshwater and floats in saltwater. Why does this occur? Explain your answer. * 4. Science Practices: A teacher shows students that a regular Coke can will sink in water but Diet Coke can will...
how can we tell if a new substance is made when we heat a solid?
can you help me figure out the following: part a: Calculate the specific gravity for aluminum and for brass. part b: Calculate the specific gravity for cork. part c: Calculate the specific gravity of the isopropyl alcohol. Experiment 9 Specific Gravity (Archimedes Principle) Read the Theory section on pages 9-2 & 9-3. Specific gravity is defined as the density (mass per unit volume) of a substance relative to the density of (liquid) water: s p/po, where pe is the density...
As you all know, I am a very weak person: I can only exert a force equivalent of a 10 Kg mass falling under gravity. As a Physicist, I can think of a way to lift a 1000 lbs (pounds) car. Design a system using fluid properties we have learned that will allow me to do that.
How can you tell which of the two following equations to use when solving problems and why do the two different equations exist? Why does one have moles and the other mass? How does this affect how we find internal energy for instance? I know that U= Q- W but wouldn't know which Q to use. CynAT specific mass change in heat added heat temperature
How do you know if it’s partial sum of arithmetic or geometric? 11.4 3. Find the sum of the 1st 10 terms of the seauence,-4,1,6,...
