Answer:
eyes
Explanation:
It is because the mouth, large intestine and stomach comes in the digestive system abd eyes doesn't.

Here we have to identify the sample which need more energy to heat the sample 1 degree Celsius.
Among the given elements magnesium will require more energy than the others to heat.
As per the definition of specific heat of a compound, the amount of heat required to increase the temperature of the material 1 degree Celsius is the specific heat of the material.
The given data are-
substance specific heat
Lead 0.129
Tin 0.21
Silver 0.235
Iron 0.449
Calcium 0.647
Granite 0.803
Aluminium 0.897
Magnesium 1.023
From the given data lead, magnesium, iron and aluminium have the specific heat 0.129, 1.023, 0.449 and 0.897 respectively. Thus magnesium will require more energy than the others to heat.
The correct answer is B.
Strong acids completely dissociates to give hydrogen ions . Weak bases can only partially dissociate to give hydroxide ions .
Therefore when equal amounts of acid and base are mixed, while Acid is completely dissociated and gives out hydrogen ions but base only gives out a fraction of hydroxide ions.
Therefore number of hydrogen ions in the solution will be higher than hydroxide ions, resulting in an acidic pH. Therefore pH <7
Answer:
hi
Explanation:
There is enough energy in air at room temperature to change some liquids to gases. The temperature of ice water is lower than the temperature of dry ice in alcohol. Carbon dioxide can change directly from the solid phase to the gaseous phase. ... Absolute zero is the temperature at which there is no molecular motion.
Answer: True
