Why are temperature variations greater over dry land than they are over water?
Temperature variations are greater over dry land than over water due to the differing heat capacities of land and water. Land heats up and cools down more quickly than water because it has a lower specific heat capacity, meaning it requires less energy to change its temperature. Additionally, water has a high heat capacity and can absorb and retain heat more effectively, which moderates temperature changes. This results in more extreme temperature fluctuations on land compared to the more stable temperatures typically found over bodies of water.
How would the measured value of specific heat be affected if some boiling water were carried over with the sample?
If boiling water were carried over with the sample, it would increase the measured value of the specific heat. The excess heat energy from the boiling water would contribute to raising the overall temperature of the sample, leading to a higher specific heat value being calculated.
Specific heat of water equals?
4.18 joules over grams n temp
Most specific heat capacities are found by combining a substance with another with a known specific heat usually water. But How do chemists know the specific heat capacity of water in the first place?
The specific heat capacity of water was initially determined through experiments involving measuring the temperature change when a known amount of water absorbs a certain amount of heat. The relationship between the heat absorbed, temperature change, and mass of water was used to calculate the specific heat capacity of water. This value has been confirmed and refined over time through numerous experiments and calculations.
How can sea temperature change a hurricane?
As I understand it, hurricanes develop, and enlarge as a result of absorbing ENERGY in the form of HEAT from the water over which they travel.Therefore, the greater the heat, the greater the chances of a hurricane growing larger and more violent. And the converse of that is also true: As the temperature of the mass [water or land] over which the hurricane travels decreases, the greater the tendency for it to weaken and dissipate.
The specific gravity of a product can be found on the material safety data sheet. How do you know if a product will sink in water?
If the specific gravity of a product is greater than 1, it will sink in water. Specific gravity is a ratio comparing the product's density to the density of water, so a value greater than 1 means the product is denser than water and will sink.
What can you say about the specific gravity of an object that floats in water and the specific gravity of an object that completely submerges in water?
An object that floats in water has a specific gravity less than 1, indicating that its density is less than that of water. An object that completely submerges in water has a specific gravity greater than 1, indicating that its density is higher than that of water.
Sodium hydroxide in water has a pH of?
The pH is greater than 7, but beyond that the specific pH will depend on the concentration.
How do you determine the specific heat capacity of an object by method of cooling?
To determine the specific heat capacity of an object by the cooling method, you would first heat the object to a known temperature and then immerse it in a known volume of water at a lower temperature. By monitoring the temperature change of the water and the object over time, you can calculate the specific heat capacity of the object using the formula q = mcΔT.
From which surface is evaporation greater land or ocean?
Evaporation is generally greater over the ocean than over land due to the larger surface area of water bodies and the availability of moisture in the atmosphere. The ocean has a higher evaporation rate compared to land surfaces due to the water's ability to store heat and release it slowly over time.
What does the high specific heat of water have to do with the convection currents in the air at the seashore?
Water'specific heat capacity is 4200 J/Kg°C . This high specific heat capacity suggests that the water will travel long distances without losing heat . This makes the convection currents in the air last longer.
Can mica float on water?
Mica is over twice as dense as water, so unless the mica is in the shape of a boat, it will sink.
