Answer:
B
Explanation:
Relative humidity can be found by subtracting dry bulb reading minus wet bulb reading. The greater the difference, the lower the relative humidity. B as the greates difference, therefore it indicates lower relative humidity.
Answer:Explained
Explanation:
Given
mass of aluminium kettle(
)=1.05 kg
(a)Heat capacity of the kettle=Heat capacity of Aluminium

(b)Heat is required to increase the temperature of this kettle from 


Q=71.82 kJ
(c)If kettle contains water 1.25 L of water i.e. 1.246 kg of water then heat required to raise the temperature from 23 to 99


Q=71.82+396.20=468.028 kJ
Answer:
The two samples have identical properties because they are the samples of the same element. Intensive properties are properties of matter that do not change depending on the amount of matter. Luster, reactivity, and ductility are all intensive properties. That is why the two samples can be different sizes or shapes, but have identical properties.
Answer: it is likely soluble in water
It will likely light up a bulb in a conductivity apparatus
It will likely have a high melting point
Explanation:
There are many things that we do in our daily lives that involve energy changes. For example ,when you hold your textbook in the air, you are giving it potential energy. Another example is an object in simple harmonic motion. Energy is constantly being transferred from one from to another, potential to kinetic.
