Explanation:
Single displacement reaction is defined as the reaction in which more reactive element displaces a less reactive element from its chemical reaction. The reactivity of metal is determined by a series known as reactivity series. The metals lying above in the series are more reactive than the metals which lie below in the series
An Economic Good that I have used today is a laptop and an Economic Service that I have used today is bank.
Economics can be defined as a field of science that is focused on the analysis and examination of various principles that influence the production, demand and supply of goods and services.
Another purpose for the studying economics is to examine certain principles that influence the production of goods and services.
So, we can conclude that economics states that we are all consumers and a consumer is someone who uses both economic goods and services.

The statement that is true of thermometers is; The temperature reported by a thermometer is never precisely the same as its surroundings.
<h3 /><h3>What is the function of thermometer in an experiment?</h3>
In the experiment to determine the specific heat of a material, the theory will be one which explains that when a heat interchange takes place between two bodies that were having different temperatures at the beginning, the quantity of heat the warmer body looses is equal to that gained by the cooler body to reach the equilibrium temperature. This is true only if no heat is lost or gained from the surrounding.
Now, If heat is gained or lost from the surrounding environment, the temperature readings by the thermometer will be incorrect. The experimenter should therefore have in mind that for accurate results, the temperature recorded by the thermometer is similar to that of the surrounding at the beginning of the experiment and if it differs then note that heat is either gained or lost to the environment.
