1. )Which of the following identifies a measurement its si unit, and the tool most commonly used to measure it ? "2/15/XX, 1600, 101.2, Gloria Jackson, MA" What does temperature measure? Which of the following statements is true concerning the units of temperature. The temperature measured is more sensitive and accurate than that from a mercury thermometer. a. kilogram b. liter c. meter d. Kelvin. The previous syntax defines unit-name as a unit of measure. SI unit of temperature; 273.15 K = 0 ºC kilogram (kg) standard SI unit of mass; 1 kg = approximately 2.2 pounds length measure of one dimension of an object liter (L) (also, cubic decimeter) unit of volume; 1 L = 1,000 cm 3 meter (m) standard metric and SI unit of length; 1 m = approximately 1.094 yards milliliter (mL) 1/1,000 of a liter; equal to 1 cm 3 Which of the following statements is true concerning the units of temperature measurement? (A) 523.2 K (B) -209.7 K (C) 709.7 K (D) -23.2 K (E) 23.2 K. Answer : A. Thnx! The 2018 General Conference on Weights and Measures decided that effective from May 20, 2019, the unit would be defined such that the Boltzmann constant … However, Celsius is also often used as a measure of temperature. s. Log in for more information. The SI unit of temperature as per the International System of Units is Kelvin which is represented by the symbol K. The Kelvin scale is widely accepted or used in the field of science and engineering. The closeness of a measurement to its true value is a measure of its: a. accuracy b. reproducibility c. usefulness d. precision 36. The first centigrade scale (made up of 100 degrees) is attributed to the Swedish astronomer Anders Celsius, who developed it in 1742. The instrument which is used for measuring temperature is a thermometer. This makes the kelvin scale essential to scientists who calculate the temperature of objects in the cold reaches of outer space. Use plastic covers to prevent the spread of infection. Which of the following shows a tympanic measurement? What humidity did you ±nd? Measurements can be affected by infection, activity, eating, and metabolism. Kelvin (K) temperature unit of measurement: Boltzmann constant, defined as a change in thermal energy of 1.380 649 × 10 −23 joules. It is a measure of the energy transfer of a system due to a change in temperature or phase. The kelvin (the word is spelled with a lower-case k) is the unit of temperature in the International System of Units (SI). Which graph of temperature versus time for that night looks most, 6. In any case, here is the relation between Celsius Fahrenheit, and Kelvin; Question. Standard Units of Measurement. Molarity changes with temperature. a. d. Internationally, °F are always used. Kelvin (K), base unit of thermodynamic temperature measurement in the International System of Units (SI). 15. The S.I. 1 km is 8 °C, what stability does the atmosphere demonstrate at this level? The kelvin scale is the only unit of measurement to include the temperature for "absolute zero," the total absence of any heat energy. c. The relative humidity is 100% and the air is saturated. Record your answer from Lab Exercise 3, Question 3: ___________________. (A) 523.2 K (B) -209.7 K (C) 709.7 K (D) -23.2 K (E) 23.2 K. Answer : A. )length,meter,ruler B. Use your own lined notebook paper or graph paper. If you lift a 15 °C air bubble from the surface to 1 km height and the. 16. Nothing can be colder than absolute zero, which is the point at which all molecular motion ceases. ", 277,629 students got unstuck by CourseHero in the last week, Our Expert Tutors provide step by step solutions to help you excel in your courses. In the United States, °C are used for surface measurements. 26 questions involved need solutions for a guide. Water expands as the temperature increases, so the volume of the solution also increases. Three different people weigh a standard mass of 2.00 g on the same balance. b. The temperature of a body in its own state of thermodynamic equilibrium is always positive, relative to the absolute zero. c. Internationally, °C are used for surface measurements. When temperature increases in an object, the molecules inside it start to move faster, and this causes the object to expand. Immediately get someone with experience and a Hazardous Materials kit to clean it up. Density is the measure of the amount of matter present in a space of unit volume. This is because BJTs have consistent temperature coefficient which results in smaller errors over temperature. Mole … In the United States, °C are used for surface measurements. Rømer is a temperature scale named after the Danish astronomer Ole Christensen Rømer (25 September 1644 — 19 September 1710). Meter (m) length unit of measurement: Distance traveled by light in a vacuum in 1/299,792,458 seconds. Length: Meter (m) The meter is the metric unit of length.
