Which term names the transfer of heat between two objects that are touching​
Svetlanka [38]

Answer: Conduction

Explanation:

Conduction means the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.

Meaning that its when an object touches another object and heat gets transferred.

A gas tank contains 3 gases (N2, O2, and CO2). The total pressure of the gases is 825mmHg. If Pco2 = 125mmHg and Po2= 350mmHg, w
DedPeter [7]

Answer:

350mmHg

Explanation:

Use Dalton law

Total=P gas 1+p gas 2+ P gas 3

825=P1+350+125

825=P1+475

825-475= P1

P1= 350 mm Hg

What is the molar mass of glucose, C3H603?
ziro4ka [17]

Answer:

The mass percentage of carbon can be found easily using the molar mass of C6H12O6, 180.1559 g/mol. We need to find the mass of the glucose produced, so we multiply the number of moles of glucose by its molar mass. C6H12O6 = CO2 + C3H6O3 + CH3OCH3 Take fructose for example. Compound.

Specific Heat Material Copper Aluminum Gold Pyrex Specific Heat (J/g °C) 0.385 0.902 0.129 0.75 Material Water Ice Olive Oil Air
zimovet [89]

Explanation:

  • It is known that the amount of heat necessary to raise the temperature of 1 gram of a substance by 1^{o}C is known as specific heat.

Since,     q = mC \Delta T

So, larger is the specific heat of a substance less will be the change in its temperature.

Therefore, olive oil has less specific heat as compared to water. This means that olive oil would get hotter.

  • Similarly, the specific heat of gold is lesser than the given materials or metals. Hence, gold will requires less heat to rise its temperature.

As a result, water present in gold will heat readily.

  • As the relation between heat and specific heat is as follows.

              q = mC \Delta T

Therefore, calculate the amount of heat required by the water as follows.

                 q = mC \Delta T

                    = 100 g \times 4.18 J/g^{o}C \times (100 - 20)^{o}C

                    = 33440 J

or,                 = 33.44 kJ               (as 1 kJ = 1000 J)

Thus, 33.44 kJ heat would it take to raise the temperature of 100.0 g of water from 20.0^{o}C to 100.0^{o}C.
