Which units express heat capacity

Chemistry
2 answers:
vladimir1956 [14]3 years ago
7 0

Answer:

Heat capacity units: J/K

Explanation:

Heat capacity (C) is the amount of heat (Q) required to raise the temperature(T) of a substance by a unit degree.

C = \frac{Q}{T}

It is usually expressed in terms of J/K

Heat capacity is an intensive property i.e. it is not dependent on the amount of the substance. i.e, the amount of heat required to raise the temperature of 1 g of copper per kelvin would be the same as that corresponding to 100 g.

The heat capacity of a defined system is the amount of heat (usually expressed in calories, kilocalories, or joules) needed to raise the system's temperature by one degree (usually expressed in Celsius or Kelvin). It is expressed in units of thermal energy per degree temperature. To aid in the analysis of systems having certain specific dimensions, molar heat capacity and specific heat capacity can be used. To measure the heat capacity of a reaction, a calorimeter must be used. Bomb calorimeters are used for constant volume heat capacities, although a coffee-cup calorimeter is sufficient for a constant pressure heat capacity.

PolarNik [594]

Answer:

1.Magnetosphere

2.Liquid Outer core

3.Atmosphere

4.Lightening

5.Biosphere

6.Blue

7.Dolphins

8.Hydrosphere

9.Ice Caps

10.Lithosphere

11.Latitude

12.Longitude

Explanation:

The invisible field that protect us from solar radiation is called Magnetosphere.

This protective field is created by movement between solid inner core and earth's Liquid outer core.

The layer of gases is called atmosphere.

In addition to wind , rain , lightening is observed on stormy night.

Because of water earth looks Blue.

Dolphins are just one of the animals that calls the hydrosphere, its home.

Ice caps in the north and south poles.

Rocky layer of solid earth is part of Lithosphere.

Look for the latitude first ,horizontal line ...

When co2 levels are low and o2 levels are high, rubisco adds an o2 molecule to rubp. what are the consequences of this reaction?
marissa [1.9K]
Rubisco is an important enzyme that helps in making lifeless carbon of carbon dioxide into organic molecules. Rubisco takes carbon dioxide and attaches it to ribulose bisphosphate, a short sugar chain with five carbon atoms that has rubp as its shortcut. Rubisco then clips the lengthened chain into to polyglycerate pices, which are pretty flexible molecules and are also used in the feeding of the plant. Most of it is used in the photosynthesis pathway, but some of it is used to make sucrose (table sugar) to feed the rest of the plant, or stored away in the form of starch for later use. Hence, rubisco is crucial in the storing of the energy that is created from photosynthesis.
