Which choice best describes the specific heat of water compared with that of metals?

1 answer:

8 0

Answer: Specific heat capacity is the measurement of how much energy (in J) has to be added to 1 kg of a substance to increase the temperature of that substance by 1 o C. Simply, substances with a low specific heat capacity heat up quickly - but then they lose their heat quickly. Substances with a high specific heat capacity require a large amount of heat to be added to change their temperature - but then they hold their heat much longer.

Explanation: Think of heating a pot of soup on the stove and stirring it with a metal spoon. If you leave the spoon sitting in the pot for even a few minutes and you return, the spoon will be hot enough to burn your hands - and the soup will feel only slightly warmer. This happens because the specific heat capacity of the metal spoon is much lower than that of the water in the soup. Water has the highest specific heat capacity of any liquid.

Hope this helps!!!!!

a one gram sample of hematite up more space than a one gram sample of malachite. what mineral characteristic does this refer to

Gwar [14]

I think the mineral characteristics that the one gram sample of hematite taking up more space than a one gram sample of malachite is DENSITY.

The density of hematite is 5.26 g/cm³
The density of malachite is 3.6 to 4 g/cm³

Other physical characteristics of minerals are Color, Streak, Luster, Hardness, Cleavage, Fracture, Tenacity, and Crystal Habit.

What is the density of a solid that has a mass of 9.2 grams and a volume of 12.3 cm3 ? Would this object float or sink in water?

cluponka [151]

Mass=9.2g
Volume=12.3

$\boxed{\sf Density=\dfrac{Mass}{Volume}}$

$\\ \sf\longmapsto Density=\dfrac{9.2}{12.3}$

$\\ \sf\longmapsto Density=0.74g/cm^3$

Density of water =1g/cm^3

It will float in water

As with the properties of a substance, the changes that substances undergo can be classified as either physical or chemical. During physical changes a substance changes its physical appearance, but not its composition. The evaporation of water is a physical change.

(I searched that up but here’s an explanation with my own words that you can use):

Change in matter can be classified as a physical change as well as a chemical change due to the properties of substance. A physical change changes substance within its appearance but not its composition. For an example: The evaporation of water is a physical change.

There you go hopefully that helped

When NAD becomes NADH, it is being reduced and gaining chemical energy.

Nicotinamide adenine dinucleotide (NAD), a coenzyme, can exist in two forms, NAD⁺ (oxidized) and NADH (reduced form).

Electrons and protons released in catabolism reactions are attached to NAD⁺. The conversion of NAD⁺ to NADH is important reaction for production of ATP during the cellular respiration.

Reduction is lowering oxidation number because element, ion or compound gain electrons.

Chemical equation for reaction of reduction of NAD⁺ (see picture below):

NAD⁺ + 2e⁻ + H⁺ → NADH

Nicotinamide adenine dinucleotide (NAD) is made of two nucleosides joined by pyrophosphate.
