What are two major uses of a classification system for abnormal behavior?
What are two major uses of a classification system for abnormal behavior? We need a classification system for abnormal behavior for two primary reasons. First, a classification system is useful to clinicians, who must match their clients’ problems with the form of intervention that is most likely to be effective. Second, a classification system must […]
What is the strongest crystal structure?
What is the strongest crystal structure? Diamond is the hardest material known, defining the upper end of the 1-10 scale known as Moh’s hardness scale. Diamond cannot be melted; above 1700 °C it is converted to graphite, the more stable form of carbon. The diamond unit cell is face-centered cubic and contains eight carbon atoms. […]
What type of reaction is Ca OH 2 Heat?
What type of reaction is Ca OH 2 Heat? Among widely recognizable exothermic reactions is the combustion of fuels (such as the reaction of methane with oxygen mentioned previously). The formation of slaked lime (calcium hydroxide, Ca(OH)2) when water is added to lime (CaO) is exothermic. How many different elements are involved in the chemical […]
How do you test a hypothesis in an experiment?
How do you test a hypothesis in an experiment? How to Test Hypotheses State the hypotheses. Every hypothesis test requires the analyst to state a null hypothesis and an alternative hypothesis. Formulate an analysis plan. The analysis plan describes how to use sample data to accept or reject the null hypothesis. Analyze sample data. Interpret […]
What is the relation between temperature and pressure?
What is the relation between temperature and pressure? In a closed system where volume is held constant, there is a direct relationship between Pressure and Temperature. In a direct relationship, one variable follows the same change when it comes to increasing and decreasing. For example, when the pressure increases then the temperature also increases. What […]

What has more water lakes or rivers?
What has more water lakes or rivers? By comparison, freshwater comprises only 3% of the earth’s water, and surface water is only 0.3% of that 3%. Furthermore, rivers and lakes comprise 2% and 87%, respectively, of surface water. Thus, rivers contain only 0.00018% and lakes only 0.0078% of the earth’s water. Who has the most […]
Why is the voltmeter connected in parallel with a resistor when measuring its voltage?
Why is the voltmeter connected in parallel with a resistor when measuring its voltage? A voltmeter is an instrument that measures the difference in electrical potential between two points in an electric circuit. In order for a voltmeter to measure a device’s voltage, it must be connected in parallel to that device. This is necessary […]
