False. A graduated cylinder is used to measure volume, not mass. Mass is typically measured using a balance scale or other weight measuring devices.
True. The motion of an object can be measured by observing its position change over time. This can be done by using tools such as cameras, sensors, or motion detectors to track the movement of the object.
False. Volume is a measure of the amount of space occupied by an object, while the quantity of matter is typically measured by mass. They are related but not the same, as the density of an object can affect its volume even when the quantity of matter remains constant.
False. The wavelength of a wave is actually measured from crest to crest, or trough to trough, not from crest to trough.
False. Heat is measured in units of energy such as calories or joules, not in degrees Celsius. Temperature, on the other hand, is measured in degrees Celsius.
True. Motion is always measured in relationship to a point of reference. This point of reference can be stationary or moving itself, but it is essential for determining the position, speed, and direction of an object in motion.
A hexagonal cylinder is an impossible object. If you meant a hexagonal prism then it is a polyhedron.
True. The motion of an object can be measured by observing its position change over time. This can be done by using tools such as cameras, sensors, or motion detectors to track the movement of the object.
True
A graduated cylinder is used to measure the volume of a liquid and occasionally a solid (it can be inverted and used to measure gas as well!) The cylinder is made of glass (usually Pyrex) or plastic and has measured lines with volume values noted on the lines (a.k.a. graduations.) Simply fill the cylinder with a liquid until it reaches the volume you require. When measuring the liquid level you will notice that electrostatic forces and gravity alter the shape of the liquid's surface to a crescent shape. This is called a "meniscus." In most cases the shape will look like a smile, you must make the measurement so the bottom portion of the smile shape is lined up with the graduation mark on the cylinder. Occasionally the meniscus will be close to flat or inverted like a frown, such is the case with liquid mercury. In such scenarios, the uppermost portion of the frown shape should be used for accurate measurement. To measure the volume of a small solid object of irregular shape, you can measure out a certain volume of a liquid (like water) in the cylinder, and then carefully place the solid objects in the cylinder, making sure they are completely submerged and contain no air bubbles. The water is displaced to a new reading on the graduated cylinder and the difference between the original and the final readings is the volume that the solid object occupies. Measuring the volume of a gas is more complicated to set up and explain. In general the graduated cylinder is filled with liquid and inverted in a large container filled with water. The gas reaction evolves gas through a tube, directly under the inverted cylinder, and rises to the top (the base of the inverted cylinder). The amount of gas produced will displace the water downward as it fills the top of the cylinder and can be measured using the graduations when the gas has ceased. This will give you the volume that the gas occupies. If the gas is soluble in the liquid, some may remain dissolved and give a false-low volume reading.

False
You must read from the bottom of the meniscus. In a narrow, graduated glass cylinder, water has a slightly domed surface, with the centre being higher than the side, so giving a false reading if the centre height is taken.

False, it is measured from crest to crest.
