Water and ether are placed on the palms of both the hands which will cause more cooling ether or water?
Ether has a greater cooling effect than water when smeared on your hands because of its evaporation method. Ether gets its energy from your hands. So when it evaporates, the cooling effect is greater than water.
Why is acetone cooler than water?
Acetone tends to evaporate faster than water, which causes it to have a cooling sensation when it comes in contact with the skin. This is due to the higher volatility of acetone compared to water, leading to a more rapid evaporation process that removes heat from the skin, resulting in a cooling effect.
Why cold water is made to run from lower side to upper side in distillation?
Cold water is usually made to run from the lower side to the upper side in distillation to maximize cooling efficiency. By introducing cold water at the bottom of the condenser, it can absorb more heat as it flows upwards, effectively cooling the vaporized gases and aiding in their condensation back into liquid form. This counterflow arrangement helps maintain a strong temperature gradient, which is crucial for successful distillation.
Why is the cooling water in the liebig conden ser made to run counter current to the flow of the distillate?
Running the cooling water in the Liebig condenser counter-current to the distillate flow improves the condensing efficiency by maintaining a larger temperature difference between the vapor and the cooling water throughout the length of the condenser. This allows for more effective heat transfer and a higher rate of condensation.
Is cold water more or less dense than warm water?
cold ocean waer has more dense than warm water.
What is the great cooling effect produced by water evaporating, and how does it relate to its high evaporation rate?
The great cooling effect produced by water evaporating is called evaporative cooling. When water evaporates, it absorbs heat from its surroundings, causing a cooling effect. This cooling effect is related to water's high evaporation rate because the faster water evaporates, the more heat it can absorb, leading to a greater cooling effect.
What makes the sea water cold?
cooling of seawater is caused by the evaporation of surface water which takes latent heat from surrounding water molecules, similar to the effect of sweating. Cooling of seawater is also due to brine acceptance, if the water becomes more saline, it will sink as it is heavier than the surrounding water masses and thus cooling as water which becomes more dense has a lower maximum temperature, and pressure causes water to become colder.
Why is a piece of ice more effective in cooling a drink than the same mass of cod water?
A piece of ice is more effective in cooling a drink because it has a higher specific heat capacity than cold water, meaning it can absorb more heat while melting without significantly increasing in temperature. As the ice melts, it draws heat from the drink, cooling it more efficiently than cold water, which has already reached a stable lower temperature.
Water and ether are placed on the palms of both the hands which will cause more cooling ether or water?
Ether has a greater cooling effect than water when smeared on your hands because of its evaporation method. Ether gets its energy from your hands. So when it evaporates, the cooling effect is greater than water.
Which hot or cold water will freeze faster?
In some cases, hot water can freeze faster than cold water due to the Mpemba effect. This phenomenon occurs because hot water can evaporate more quickly, which reduces the volume of the water and leads to faster cooling. However, there are many variables at play, so it is not a reliable method for freezing water quickly.
Why is the hot water are prone to be frozen?
Hot water can freeze faster than cold water due to a phenomenon called the Mpemba effect. This effect occurs because hot water can evaporate more quickly, losing some of its volume and cooling faster. Additionally, hot water may have fewer dissolved gases, which can also aid in faster freezing.
Is rigor mortis slowed in drowning victims?
No. It depends on the surrounding temperature and the temperature of the water.
Why cooling effect of ice at 0 degree Celsius is more than same amount of water at 0 degree Celsius?
Water at 0 oC is ice.
What happens when connection for chilled water FCU Coil is reveresed?
the density of water is higher than the copper coil it doen not effect the gravitational force, because of the higher water density, the water try to achive the area of coil as we know the copper is the good conductor of cooling it absorb the cooling soon, we get the more cooling effect where air to be pump,if we does reverse connection in fcu so, cause of gavitional force water water will travel through the ciol soon and rusult into less cooling effect.as copared to previous connection
Why is acetone cooler than water?
Acetone tends to evaporate faster than water, which causes it to have a cooling sensation when it comes in contact with the skin. This is due to the higher volatility of acetone compared to water, leading to a more rapid evaporation process that removes heat from the skin, resulting in a cooling effect.
What is continental effect?
A place away from sea has warm or hot summer and cold winter.this is called the continental effect
Will water leaking into engine cause a crack?
YES! if you get your car nice and hot on a drive of 10min or more, warm to cold water can cause local cooling, and couse stress cracks
