What is the effects of temperature? An increase in the temperature of a system favors the direction of the reaction that absorbs heat, the endothermic direction. Absorption of heat in this case is a relief of the stress provided by the temperature increase. For the Haber-Bosch process, an increase in temperature favors the reverse reaction. […]
Is it safe to jump into a pool?
Where do you look first at an intersection?
Where do you look first at an intersection? Before you enter an intersection, look to both the left and right for approaching vehicles or crossing pedestrians. Look to your left a second time, as vehicle approaching from your left will be closer than those approaching from your right. What are the two basic rules for […]
How many images are formed when two plane mirrors are inclined at an angle of 90 degree?
How many images are formed when two plane mirrors are inclined at an angle of 90 degree? Interestingly, a single mirror produces a single image; another single mirror produces a second image; but when you put the two single mirrors together at right angles, there are three images. What is the angle between 2 plane […]
Can you hear the siren inside an ambulance?
Can you hear the siren inside an ambulance? Yes, patient compartments of ambulances aren’t sound proof, so the patient and crew can hear the siren. That being said, it’s worth noting that: The siren speakers are in the front of the vehicle, on the outside, pointing away, toward the traffic ahead. Why do ambulances have […]
What is the volatile substance?
What is the volatile substance? Definition. Volatility describes how easily a substance will vaporize (turn into a gas or vapor). A volatile substance can be defined as (1) a substance that evaporates readily at normal temperatures and/or (2) one that has a measurable vapor pressure. The term volatile usually applies to liquids. How do you […]
What are the phases of the general adaptation syndrome?
What are the phases of the general adaptation syndrome? The general adaptation syndrome (GAS), developed by Hans Selye, describes the pattern of responses that the body goes through after being prompted by a stressor. There are three stages: alarm, resistance, and exhaustion. Which is the last stage in general adaptation syndrome? After an extended period […]
How does deadweight work?
How does deadweight work? Dead weight testers are a piston-cylinder type measuring device. They work in accordance with the basic principle that P= F/A, where the pressure (P) acts on a known area of a sealed piston (A), generating a force (F). The force of this piston is then compared with the force applied by […]
Does a heat pump circulate water?
Does a heat pump circulate water? Heat Pump is an energy efficient water heating system. It uses a vapour compression cycle similar to that of an air conditioner. The Heat Pump operates using a controller which manages the water circulation pump. Why is a water source heat pump more efficient than an air to air […]
