Answer:
b- The heat capacity ratio increases but output temperature don’t change
Explanation:
The heat capacity is the amount of energy required to raise the temperature of a body, by 1 degree. On the other hand, the specific heat capacity is the amount of heat required to raise the temperature of a of unit mass of a material by 1 degree.
Heat capacity is an extensive property meaning its value depends on the amount of material. Specific heat capacity is found by dividing heat capacity by the mass of the sample, thus making it independent of the amount (intensive property). So if the specific heat capacity increases and the mass of the sample remains the same, the heat capacity must increase too. Because of that options c and d that say that heat capacity reamins same are INCORRECT.
On the other hand, in which has to be with options a and b both say that the heat capacity increases which is correct, but about the output temperatures what happens is that if we increase the specific heat capacity of both fluids that are involved in a process of heat exchange in the same value, the value of the output temperatures do not change so only option a is CORRECT.
0.98 g/ml the density of an object can be measured by dividing its mass
They are the opposite because opposites attract and the same retract
Answer:
More reactants and fewer products
Explanation:
If reaction is exothermic it add heat to the environment, so when we add more heat the reaction will move in opposite direction. So, more reactants and fewer products will be formed.
Answer:
The answer to your question is: water, polar solvent.
Explanation:
Data
sample of CaCl2
Solid copper this option is incorrect because in order to dissolve something the solvent must be liquid and this is a solid solvent.
water, I think this option is right, because CaCl2 is ionic and water is a polar solvent, CaCl2 will dissolve in water.
a polar solvent, CaCl2 will dissolve is a polar solvent like water, this option is correct.
hexane, CaCl2 will not dissolve in hexane because hexane is a non polar solvent and CaCl2 is ionic. This option is wrong
a nonpolar solvent This option is not right, CaCl2 will only dissolve in polar solvents.
liquid mercury, This option is wrong, mercury is not a solvent.
