How does the phrase of water affect its specific heat capacity?
It is because the density increases as you add salt and with all other substances the higher the density the lower the specific heat. For example water has a density of 1000 Kg m -3 and a specific heat of 4186 J/Kg. On the other hand copper has a density of 8960 Kg m -3 and a specific heat of 385 J/Kg.
Why would hydrogen make a better coolant than water?
Water is called a universal coolant because it can cool the machines which has been so hot after the process.the water is pumped into the machine where it comes out as steam which can be used for other purposes.The steam has a lot of energy taken from the machines. So nice ah............
What mass of water is required to absorb 4.7 times 10 5 J of energy from a tea kettle while the temp increases from 302K to 357K the specific heat of water is 4186J kg?
0.20 Kg or 200 g Specific heat is 4186 J * Kg * Change in temperature of either K or C Thus Kg = 47000 J / (4186 J * 55 K) = .20 Kg The answer to four digits is 0.2041, but the amount of joules you have only has two significant figures, so the final answer would only have two significant figures.
What has higher specific heat water or lead?
Water has much higher specific heat than lead. All metals have fairly low specific heat values.
How are specific heat of water and ice the same?
That is how specific heat is defined. When you measure something you have to measure it relative to some point of reference. In specific heat it was agreed upon that water was to be the standard and its specific heat would be one. Therefore everything else is measured relative to water.
Specific heat of blood?
4186 J/(kg C)
What is the specific heat value of ice?
* Specific heat capacity water liquid 4186 J/kgK "typical" ... 4210 J/kgK @ 275 K ; minimim 4178 J/kgK @ 308 K ; 4215 @ 370 K * Specific heat capacity water solid is 2050 J/kgK@ 270 K, drop to 1392 J/kgK @ 175 K * Specific heat capacity water vapor is 1890 J/kgK @ 375 K, up to 2000 J/kgK @ 575 K
How quickly do water attract heat?
Water does not attract heat. Water holds heat, water transfers heat from hot to cold, water changes state. ---- Well, heat isn't really the correct term. Water attracts thermal energy. Each substance has a different Specific Heat Capacity. Water has a Specific heat Capacity of 4186 J/kg. That means that it takes 4186 J/kg of energy in order to make one kg of water go up by one degree.

What is the heat loss?
Heat loss due to change in temperature: Q = mc(T2-T1) Heat loss due to change in phase: Q = mL c and L are constants that are specific to each compound at certain temperatures. For water, we usually take c to be 4186 J/(kg*K).

How many joules of energy are required to raise the temperature of 20g of aluminum from 10 degrees C to 15 degrees C?
Heat energy Q = mass x specific heat capacity x temperature change. Q = m*c*delta T Q = Joules m = kg c (aluminum) = 895.8 J/kg delta T = degr.C temp. change Answer: Q = (20/1000) x 895.8 x 5 = 89.58 Joules (Specific heat capacity of aluminum is obtained by multiplying its specific heat of 0.214 with c of water which is 4186 J/kg = 0.214 x 4186 = 895.8 J/kg).
What has higher specific heat water or lead?
Water has much higher specific heat than lead. All metals have fairly low specific heat values.
What is the specific heat value for water?
The specific heat value for water is 4.18 J/goC.
Water has a relatively low specific heat?
The specific heat of water is high. An example of an object with low specific heat would be a metal pan. Since specific heat is the energy needed to raise 1g of something 1 degree Celsius, water would have a high specific heat.
