How will the candle contributes to the pressure and temperature of gases inside the glass?

The candle contributes to the pressure and temperature of the gases inside the glass because of the increasing temperature the lit of the candle disposes into the gas molecules inside and as these gas molecules rise in temperature they become unsettling and since heat makes gas molecules robust the area becomes smaller for them to be ecstatic and as the dynamics is explained p=f/a the pressure increases.

According to the image, identify the number of neutrons in the most common isotope of aluminum.
wolverine [178]

Answer:

The number of neutron in the Aluminium Isotope is :

B. 14

Explanation:

Isotopes : These are the atoms which have same atomic number but have different mass number.

<u>This image shows the average atomic mass of Al element because it is in decimals</u>.

Atomic mass = 26.98154

(Note : mass number of single isotope can never be in decimals)

It is the average of mass of different isotopes of Al

Major Isotopes of _{13}^{26.98154}\textrm{Al} are :

  1. _{13}^{26}\textrm{Al}......atomic mass = 26
  2. _{13}^{27}\textrm{Al}.......atomic mass = 27

mass of Al given in image(26.98) is nearly equal to mass of 2nd isotope(27)

mass of _{13}^{26.98154}\textrm{Al}\ \approx 27

Now calculate the neutron in _{13}^{27}\textrm{Al}

Number of neutron = mass number - atomic number

                                = 27 - 13

Number of neutron = 14

(Atomic mass is same as mass number)

What is the difrence beetween thermal energy and temperature
bagirrra123 [75]

Answer:

Hope this helps

Explanation:

Thermal energy, which is more commonly known as heat, is a form of energy. It is measured in joules. Thermal energy is an internal energy for a given system. Thermal energy is the cause for the temperature of a system.

Temperature is the measureable thermal property of a system. It is measured in Kelvin, Celsius, or Fahrenheit. The SI unit for temperature measurement is Kelvin.

Differences:

Thermal energy is not a directly measurable quantity whereas temperature is a measurable quantity.

• The temperature of an object can take negative values depending on the unit system used to measure the temperature, but the thermal energy of a system cannot be negative.

• Temperature is measured in Kelvin whereas thermal energy is measured in Joule.

• An object can lose or gain thermal energy in a state transition without changing the temperature of the system.

The plant chemical which absorbs sunlight and helps make cell food is:
nadya68 [22]

Answer:

photosynthesis

Explanation:

The process by which land plants produce their own food using sunlight and carbon dioxide is known as photosynthesis (Figure 1). While carbon dioxide is absorbed by the leaves, the sunlight is captured by a chemical molecule in the plant, called chlorophyll (Chl).
