Explain what determines the viscosity of a liquid?
the shape and size of the molecules that the fluid consists of, if they are big, wavy molecules then the liquid will be viscous because the molecules struggle to move over each other.
Are all molecules the same size?
No, there is a huge variation in size. DNA and protein molecules are relatively huge. Water and oxygen molecules are quite small. Hydrogen is the smallest.
A qualitive observation?
A qualitive observation is an observation of a product of a reaction which cannot be measured numerically, e.g. colour, state of matter. A quantitive observation is an observation which can be measured, e.g. size, volume.
What is Formula for residual defect density in QA?
No. of know defects in product/ size of the product Size of product: Total lines of Code or Total FP's
What happens to the size of the molecules during a phase change?
the hotter it gets, the bigger the size will be
What are the dimensions of product mix?
There are no set dimensions of product mix. It depends on the size of the company, number of products, product lines, and variations of each product.

Does the grain size of salt change when mixed in water?
No. the molecules are simply separated from each other and mixed with the water.
What is the meaning of aesthetics and Ergonomics in dt?
Aesthetics: The way the product looks e.g: shape, form, colour, etc. Ergonomics: The size of the product compared to the user. i.e: Is is small compared to the user?, etc.
When doing gel electrophoresis why do researchers add a ladder made up of molecules of known size?
to help the researchers identify the size of each molecule after the separation has occurred
Are molecules and X-rays the same size?
No. molecules are smaller.
Are all molecules the same size?
No, there is a huge variation in size. DNA and protein molecules are relatively huge. Water and oxygen molecules are quite small. Hydrogen is the smallest.
How many ways can you classify a square?

A qualitive observation?
A qualitive observation is an observation of a product of a reaction which cannot be measured numerically, e.g. colour, state of matter. A quantitive observation is an observation which can be measured, e.g. size, volume.
Are calories the same size as molecules?
A calorie is a measurement of energy and has no size.
What are congruent objects?
Congruent objects are two or more objects that have the same shape and size, where one object can be mapped onto the other through rigid motions such as translations, rotations, and reflections. Essentially, congruent objects are identical in every way except for their position and orientation in space.
