Consider the following statements about electromagnetic radiation and decide whether they are true or false. If they are false, correct them, (a) The total intensity of radiation emitted from a black body at absolute temperature T is directly proportional to the temperature, (b) As the temperature of a black body increases, the wavelength at which the maximum intensity is found decreases, (c) Photons of radio-frequency radiation are higher in energy than photons of ultraviolet radiation. 

Consider the following statements about electromagnetic radiation and decide whether they are true or false. If they are false, correct them, (a) Photons of ultraviolet radiation have less... 

Two students are assigned two pure compounds to investigate. They observe that compound A boils at 37°C and compound B at 126°C. However, they run out of time to make any additional measurements, so make the following guesses about the two compounds. In each case indicate whether the guess can be justified by the data, is in error, or could be either true or false. Justify your answers, (a) Compound B has the higher molar mass, (b) Compound A is the more viscous. 

Are the following statements true or false (a) If there is an atom present at the corner of a unit cell, there must be the same type of atom at all the corners of the unit cell, (b) A unit cell must be defined so that there are atoms at the corners. 

Are the following statements true or false (a) Because cesium chloride has chloride ions at the corners of the unit cell and a cesium ion at the center of the unit cell, it is classified as having a body-centered unit cell, (b) The density of the unit cell must be the same as the density of the bulk material, (c) When x-rays are passed through a single crystal of a compound, the x-ray beam will be diffracted because it interacts with the electrons in the atoms of the crystal, (d) All the angles of a unit cell must be equal to 90°. 

Determine whether each of the following statements is true or false. If a statement is false, explain why. (a) For a reaction with a very large equilibrium constant, the rate constant of the forward reaction is much larger than the rate constant of the reverse reaction, (b) At equilibrium, the rate constants of the forward and reverse reactions are equal. 

State whether the following statements are true or false. If false, explain why. (a) The dose equivalent is lower than the actual dose of radiation because it takes into account the differential effects of different types of radiation, (b) Exposure to 1 X 1 ()x Bq of radiation would be much more hazardous than exposure to 10 Ci of radiation, (c) Spontaneous radioactive decay follows first-order kinetics, (d) Fissile nuclei can undergo fission when struck with slow neutrons, whereas fast neutrons are required to split fissionable nuclei. 

A quiz in true or false and short answer format, designed to allow participants to check out their knowledge and understanding of substance misuse and other risky behaviours. 

The quiz consists of 45 questions designed to be suitable for young people aged nine to ten. The first three sheets contain a total of 40 questions, which all require answers of either true or false . The fourth sheet has five questions which require short paragraph-length answers. The teacher or group leader can decide on the length of the quiz to suit the participants and the time available. 

Infrared absorption detectors arc available for hple, although they have never become very popular. From what you know about ir spectrometry and what you have read so far about hple detectors, see if you can decide whether the following statements are true or false. 

This statement might belong to the "True" set with a membership of, say, 0.9, and to the "False" set with a membership of 0.1. Statements that in Boolean logic are either true or false, but not both, can in fuzzy logic be simultaneously...
