What is the difference between metaporphic and igneos rock?
The difference between metaporphic and ignous rock are that ignous rock is formed by cooling of magma and metaporphic is formed by temperature and pressure changes inside the earth
What is the reason for cooling of lava on earth's surface?
1) The temperature difference between the lava an its surroundings. 2) At the surface heat can be radiated away
Difference between chilled and cold water?
well chilled water temperature is below 40C but higher than 00C. where as cold water which we get from cooling tower is usually about 200C to 360C but below our body temperature.
What is newtons law of cooling?
AnswerNewton's law of cooling describes the rate an object will cool at when placed in surroundings of lower temperature. The law is derived by some basics of calculus, but based on one fact: the rate of cooling of an object is proportional to the difference in temperature between the surroundings and the object. It does assume some things and simplifies others (such as where the energy goes after leaving our object and the energy flow through the object between areas with different temperature - inside and outside) but is generally a very good approximation. Various forms of the original equation can be used depending on purpose, but solving is a lot simpler. dTt/dt = -ΔTt/t0, where Tt is the temperature of the object at a given time, t is time, and t0 is a time constant. This is a differential equation, and can be integrated to give us a solution: ΔTt = ΔT0 * e-rt, where r = 1/t0 is the time constant and e is the natural log base.
What factors causes the difference in the size of crystals formed?
factors include: saturation, rate of cooling, temperature, and the crystal itself...
Definition of cooling constant?
newton's cooling constant is defined as the ratio b/w change in temperature and difference in temperature of hot body and temperature of surrounding
Does the tea cool at constant rate?
No. It cools at a rate proportional to the difference between its temperature and that of it's surrounding. The cooler it gets, the closer it will get to room temperature, and the cooling slows down.
Why does tea cool at a constant rate?
It doesn't. The rate at which it cools is proportional to the difference between its temperature and that of the surrounding air. The cooler it gets, the lower that difference gets and the cooling will slow down.
What is newton's cooling law?
rate of change of cooling is directly proportional to the temperature distance between the body and the surrounding at the instant.
Newton's law of cooling applies to objects that are?
Newton's law of cooling applies to objects that are both heating and cooling. Newton's Law of Cooling states that the rate of change of the temperature of an object is proportional to the difference between its own temperature and the temperature of its surroundings.
How would you express Newtons Law of Cooling in word form?
Newton's Law of Cooling states that the rate of change of the temperature of an object is proportional to the difference between its own temperature and the ambient temperature (i.e. the temperature of its surroundings).
What is the difference between cooling and chilling?
Chilling is the reduction in temperature of the required solvent below than its wet bulb temperature while the rest is considered as cooling i.e. if we are only reducing the temperature of solvent to an extent such that the final temperature is above its wet bulb temperature than it will be considered as COOLING.
If wet bulb temperature is 35 and outlet water temperature from cooling tower is 25 then the cooling tower approach will be effective and what is the solution?
The Approach is the difference between wet bulb temperature and outlet water temperature from cooling tower. That means , in this case, Approach = 35-25=10 degrees.
What cools faster fresh water or salt water?
The rapidity of cooling depends on the temperature difference between the two materials.
What is the difference between metaporphic and igneos rock?
The difference between metaporphic and ignous rock are that ignous rock is formed by cooling of magma and metaporphic is formed by temperature and pressure changes inside the earth
Does the tea cool at a constant rate?
The rate that tea cools will change with the temperature difference between the tea and the ambient temperature. The larger the difference between the two, the faster the rate will be. As the tea cools closer to room temp, the rate of cooling will decrease.
How much shade does it take to change the temperature?
There is no straight forward answer for this, Newton described this in his Law of Cooling. The rate of cooling (change in temperature) is proportional to the difference in temperature. Here is an example, let's say you shade a area on the ground, when you remove the shade and expose it to the sun, the rate of cooling will be rapid at first because the difference between the shaded area and the sun's radiative temperature are greatest. Then the temperature will begin to level off as the two temperatures begin to reach an equilibrium.
