What Are The Applications Of Chemical Reaction? Chemical reactions are used to produce most of our energy. Chemical reactions are used extensively to test, identify and analyse a wide range of materials (for example, pool testing kits and forensic tests from television shows such as ‘CSI’). How are differential equations used in chemical engineering? 3
Which Cycle Is The Most Efficient Of These For The Same Compression Ratio A Otto Cycle B Diesel Cycle? For same compression ratio, the efficiency of an Otto cycle is higher than that of the diesel cycle. Which cycle is the most efficient of these for the same compression ratio? Explanation: Otto cycle is more
What Is Relation Between CP And CV? The specific heat of gas at constant volume in terms of degree of freedom ‘f’ is given as: Cv = (f/2) R. So, we can also say that, Cp/Cv = (1 + 2/f), where f is degree of freedom. What is the relationship between CV and CP for
Which Process Is Always Exothermic? Because the molecules of water vapor touching the cold glass will lose their heat, slow down, and become liquid droplets. Therefore, condensation is exothermic, because heat must be removed from the gaseous molecules in order for them to condense. 3. Which reactions are always exothermic? Combustion: This reaction will always
Can Energy Leave A Closed System? A closed system does not allow matter to enter or leave, but does allow energy to enter or leave. … An isolated system does not allow either matter or energy to enter or leave. A thermos or cooler is approximately an isolated system. Does energy always stay in a
Is It Possible To Increase The Thermal Energy Temperature Of A System Without Adding Heat To It? Adding heat, however, does not always increase the temperature. For instance, when water is boiling, adding heat does not increase its temperature. … In general, whenever there is a change of state, such as the solid-liquid or the
Can Energy Be Lost Or Created? The law of conservation of energy How can energy be wasted but not destroyed? Energy cannot be made or destroyed. … When energy is transformed or transferred only part of it can be usefully transformed or transferred. The energy that is not used in this process is wasted energy.
Is Perpetual Motion Theoretically Possible? Perpetual motion is the motion of bodies that continues forever in an unperturbed system. A perpetual motion machine is a hypothetical machine that can do work infinitely without an external energy source. This kind of machine is impossible, as it would violate either the first or second law of thermodynamics
How Do Black Holes Defy The Laws Of Physics? One issue with black holes is that the theories suggest that there is a singularity inside them. A singularity is a point of infinite density and infinite curvature of spacetime. … So, yes, black holes defy the laws of physics as we know them. This means
Does Entropy Always Increase In A Closed System? Figure 1: With entropy of a closed system naturally increasing, this means that the energy quality will decrease. This is why low quality heat cannot be transferred completely into useful work. Can entropy be negative in a closed system? The change in entropy of a closed system
