Specific heat is the amount of heat required to raise the temperature of a material by 1°c per what unit? a. volumeb. joulec. massd. pressuree. density

The answer would be C: Unit of Mass

C. mass

Explanation:

Specific heat is defined as the amount of heat energy required to elevate the temperature of a material by  1°C  per unit mass.

It is a physical property of a material. The standard international unit of heat capacity is joule per kelvin per kilogram (J/K/Kg).

If a substance has a high specific heat then it simply means that it will take very long to get heated but once heated it will take very long time to cool down either.

Water has highest specific heat.

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
