Why adsorption is a spontaneous process? Adsorption is a spontaneous process because there is a force of attraction existing between the adsorbate and adsorbent which releases heat energy. The delta H in this process is negative which means that the adsorption is a spontaneous process, and it is also an exothermic process. What causes adsorption? […]
What is the ratio of strong nuclear force?
What is the ratio of strong nuclear force? Concept Connections: The Four Basic Forces Force Approximate Relative Strengths Range Gravitational 10−38 ∞ Electromagnetic 10–2 ∞ Weak nuclear 10–13 <10–18 m Strong nuclear 1 <10–15 m What is the range of strong nuclear force? The nuclear force is powerfully attractive between nucleons at distances of about […]
How many joules does it take to stop a train?
How many joules does it take to stop a train? To literally stop the train dead the Hulk would need to produce almost 50 mega-joules of energy. Does a train use energy? To operate without an external power supply, the train must transport its own energy for propulsion. Traditionally, this was carried along in the […]
How many kW is a 4 ton AC?
What is the salinity level of the Dead Sea?
What is the salinity level of the Dead Sea? 342 g/kg Why Dead Sea has high salinity? When water evaporates, it leaves any impurities behind. As a result, the Dead Sea has the saltiest and most mineral-laden natural water in the world. The surface water has a salinity of about five to nine times that […]
Why do organisms need to control their internal environment?
Why do organisms need to control their internal environment? The cells that make up organisms have a big job – keeping those organisms healthy so that they can grow and reproduce. The maintenance of stable, constant, internal conditions is called homeostasis. Your cells do this by regulating their internal environments so that they are different […]
Can you drink the water from a cactus?
Can you drink the water from a cactus? Water is truly a precious resource in a desert, so, in addition to their intimidating spines, most cactus species further protect their spongy flesh with acids and potent alkaloids. These chemicals are usually too acrid for most humans to tolerate and are taxing on the kidneys if […]
What happened to the current in a series circuit?
What happened to the current in a series circuit? The same current flows through each part of a series circuit. The total resistance of a series circuit is equal to the sum of individual resistances. The voltage drop across a resistor in a series circuit is directly proportional to the size of the resistor. If […]
What are the examples of Endoskeletons?
What are the examples of Endoskeletons? Some examples of endoskeleton are cartilage, bone, etc. The hard part present outside the body which protects the soft tissues and muscles is called the exoskeleton. It is developed from ectoderm and is mostly called a non-living structure. Some examples of the exoskeleton are hair, feather, scales, horns, etc. […]
Does planning improve performance?
Does planning improve performance? Strategic planning is a widely adopted management approach in contemporary organizations. A random-effects meta-analysis reveals that strategic planning has a positive, moderate, and significant impact on organizational performance. How does planning contribute to the performance of an organization? It Helps to Set the Right Goals In particular, planning helps to critically […]
