Why do you round off numbers?
You round off numbers for several reasons. First, your final answer is no more accurate than your original measurement. If you do not round off, you will give an inaccurate picture of your measurement. Second, you round off numbers to check electronic equipment. You can not begin to add, subtract, multiply, and divide in your head as fast as an electronic piece of equipment. Still, by rounding off numbers, you can get a rough idea of what the answer should be. If the answer the computer gives is nowhere near your answer then something could be drastically wrong with some spread sheet formula. You round off money real fast to know if you have been cheated.
What piece of lab equipment would you use to determine the volume of an irregularly shaped object?
A beaker. Simply fill the beaker with a known quantity of liquid. Drop the object into the beaker, and measure the difference in the fluid levels.
What is 15x36?
The numbers 15 x 36 can be either a multiplication equation with an answer of 536. Or it can be a measurement for a picture frame size, a poster board or a piece of paper.
You paid 508 for a new piece of equipment after a 9 percent dicount?
.09*508 = 45.72: This is the 9% discount.so you paid 508-45.72 = 462.28 after the discount.
How many months is 39 days?
A month is not a standardised unit of measurement, as such it is not possible to do a conversion from days to months without an assumption being set. Questions of this nature should include an additional piece of information such as "treat a month as equal to 30 days".
What measurement of a liquid can you make with a graduated cylinder?
A graduated cylinder is a piece of laboratory equipment used to measure the volume of a liquid and are generally more accurate and precise than laboratory flasks and beakers.
What is the most appropriate piece of equipment to accurately measure 85 mL of water?
A graduated cylinder would be the most appropriate piece of equipment to accurately measure 85 mL of water. It has precise markings that allow for accurate measurement of liquid volumes.
What is a graudated cylinder?
A graduated cylinder is a tall, narrow container with volume markings on the side used to measure liquid volumes. It is commonly used in laboratories for accurate measurement of liquids.
What is the use of automatic pipette?
An automatic pipette is a piece of laboratory equipment that is used in transferring small liquid volumes. It is known to be both accurate and precise.
What piece of lab equipment would you use to measure exactly ml?
A graduated cylinder is commonly used to measure liquid volume in milliliters accurately. The markings on the cylinder allow for precise measurement of the volume of liquid.
In the laboratory volumes of liquid are usually measured with an?
In the laboratory, volumes of liquid are usually measured with a graduated cylinder. This piece of equipment has markings along the side that allow for precise measurement of the volume of liquid it contains.
Which piece of equipment can best measure the volume of ink in a pen?
A graduated cylinder would be the best piece of equipment to measure the volume of ink in a pen. This cylinder has measurement markings that can accurately indicate the volume of liquid inside it.
Why is a themometer the most accurate piece of equipment to measure temperature?
A thermometer is the most accurate piece of equipment to measure temperature because it is specifically designed for that purpose, using a narrow tube to accurately reflect the expansion or contraction of a liquid or mercury with changing temperature. The design of a thermometer allows for precise readings of temperature changes.
What piece of equipment is used to find the volume of a liquid?
A Graduated Cylinder
What type of equipment is used to determine characteristics or values using specific procedures andor methods to make a reference measurement?
A reference measurement is typically made using a primary standard, which is a highly accurate and stable piece of equipment that is traceable to a recognized reference. Examples of equipment used include calibrated rulers, thermometers, balances, and specific analytical instruments like spectrophotometers or mass spectrometers, depending on the type of measurement being made.
What is the piece of equipment that changes steam and oil vapour to liquid?
A condenser is the piece of equipment that changes steam and oil vapor to liquid. It works by cooling the vapor down until it reaches its dew point and condenses into a liquid form.
Is a graduated cylinder used for?
A graduated cylinder is a usually glass (but some are plastic) quantitative piece of laboratory equipment. Graduated cylinders are used for accurate liquid measurement. To read a graduated cylinder correctly, the volume of liquid contained is measured at the bottom of the meniscus, which is at the top of the liquid, in the exact center of the cylinder, and not at the side where the liquid touches the glass (or plastic).A graduated cylinder, measuring cylinder or mixing cylinder is a piece of laboratory equipment used to measure the volume of a liquidit is used for the precise measurements of liquids.To measure volume of liquids.Pour liquid in the graduated cylinder then find the lower meniscus (lower meniscus's lower curve of liquid's surface) read the volume off the graduations.Measurement of liquids OR a container used to find the volume of an object in Liters.
