What is the number 1 cause of work related fatalities? Motor […]
Which of the following are examples of hydrolysis reactions?
Which of the following are examples of hydrolysis reactions? Dissolving a salt of a weak acid or base in water is an example of a hydrolysis reaction. Strong acids may also be hydrolyzed. For example, dissolving sulfuric acid in water yields hydronium and bisulfate. Which is a hydrolysis reaction? Usually hydrolysis is a chemical process […]
Why do we use zero correction?
Why do we use zero correction? Zero correction is used in an instrument for removing the zero error. What is zero error and its correction? Zero error correction arises due to error in the measuring instrument. It occurs when the first marked line of the instrument like vernier calliper, micrometer screw guage etc. do not […]

What activities use energy?
What activities use energy? They include watching television, washing clothes, heating and lighting the home, taking a shower, working from home on your laptop or computer, running appliances and cooking. Residential uses of energy account for almost forty percent of total energy use globally. What is the importance of energy in points? Energy is essential […]
What is the Continental Divide and what is its purpose?
What is the Continental Divide and what is its purpose? A continental divide is a boundary that separates a continent’s river systems. Each river system feeds into a distinct ocean, bay, or sea. The Loveland Pass, pictured here, is a continental divide in Colorado that separates water flowing into the Atlantic and Pacific ocean basins. […]
What are the two main types of calorimeter?
What are the two main types of calorimeter? Some of the most common types are adiabatic calorimeters, oxygen bomb calorimeters, and differential scanning calorimeters (DSC). An adiabatic calorimeter is used to measure a “runaway reaction”, any heat generated by the sample under test causes the sample to increase in temperature, fueling the reaction. How do […]
What happens when two forces are exerted in opposite direction?
What happens when two forces are exerted in opposite direction? 1. Opposite direction :- The object do not moves his place because When the two forces act in the opposite direction , the force get cancelled when a force of same magnitude is applied on opposite direction . What happens if balanced forces are applied […]
How can we increase the speed of motor give two ways?
Why diffusion is slowest in solid and fastest in gas?
Why diffusion is slowest in solid and fastest in gas? Diffusion takes place with slowest rate in the case of solids. The rate of diffusion is almost negligible in solids. Since the particles of solid have lowest kinetic energy so they do not move. Hence, diffusion takes a long time in the case of solid. […]
