Why should you use constant value in physics and chemistry?
Physical constants are used for two main reasons. First, the quantitative predictions depend on the numerical values of the constants. An accurate knowledge of their values is therefore essential to achieve an accurate quantitative description of the physical universe. Second, the careful study of these constants can in turn test the overall consistency and correctness of the basic theories of physics themselves.
What term would you use to classify the two substance?
Chemical- the composition of the substance Physical- appearance of substance
A strong physical and psychological craving for a substance?
This describes addiction, characterized by a compulsive need to use a substance despite negative consequences. It involves both a physical dependence, leading to withdrawal symptoms when the substance is not used, and a psychological dependence, where a person feels a strong urge or craving to use the substance.
What is the use of constants and variables in programs?
to store values
How do you use the word physical properties in a sentence?
The physical properties of water will change when it freezes, turning from a liquid to a solid
What is substance tolerance and substance dependence?
Substance tolerance refers to a diminished response to a substance after repeated use, leading individuals to require larger doses to achieve the same effects. Substance dependence, on the other hand, is characterized by a physical or psychological reliance on a substance, resulting in withdrawal symptoms when not using it. Both concepts are associated with substance use disorders, highlighting the complexity of addiction and the body's adaptation to prolonged substance exposure.
What is the habitual use of a chemical substance?
The habitual use of a chemical substance refers to regularly using the substance over time, often leading to dependence or addiction. This repeated use can result in physical or psychological effects, affecting an individual's health and well-being. Examples include alcohol, tobacco, and drugs.
Explain why it is important to use constants in an experiment?
so scientist can compare result
What are symbolic constants?
A symbolic constant is a constant with a name, numeric constants are unnamed and must be retyped in the code on each usage. Generally use of symbolic constants is preferred as it makes the code self documenting and allows the compiler to catch typing errors in constant usage.
Why use constants?
Constant is the speed of light and as the speed of light cannot change it is 'constant'
A metal melts at 450 degrees celsius is the property of the metal classified as chemical or physical property?
chemical. when it melts, it doesn't mean it changed into a new substance. it just changed physical states! it is still a metal. physical state is a physical property of any substance, so when it changes physical state, as in changes to liquid, solid or gas, it is still the same substance.
