The air in a living room has a mass of 60 Kg and a specific heat of 1,020 J/kg°C. What is the change in thermal energy of the ai

arlik [135]

Answer:

Q = 306 kJ

Explanation:

Given that,

Mass, m = 60 kg

Specific heat, c = 1020 J/kg°C

The temperature changes from 20°C to 25°C.

Let Q be the change in thermal energy. The formula for the heat released is given by :

$Q=mc\Delta T$

Put all the values,

$Q=60\times 1020\times (25-20)\\\\Q=306000\ J\\\\or\\\\Q=306\ kJ$

So, 306 kJ is the change in thermal energy.

What do the Roman numerals in a cation's name indicate?

Agata [3.3K]

The Roman numerals in a cation's name indicate: THE POSITIVE CHARGE ON THE CATION

Cations are metallic atoms that loosely hold it electrons, making it easy to lose electrons.

The Roman numerals in a cation's name not only indicates the charge on the cation but it makes it easier to distinguish cations that share the same metal name.

How Many Atoms Are In 356.13 Grams Of Sn

s344n2d4d5 [400]

There are three atoms of Sn (Stannous or Tin) in 356.13 g of Sn.

One atom of Sn has the atomic mass (mₐ) of 118,71u which means:

356.13/118.71=3 atoms of Sn

The mass number (symbol A) also called atomic mass number or nucleon number is the total number of protons and neutrons in an atomic nucleus. It determines the atomic mass of atoms and it is in the periodic table.

Marvin records scientific data about Lake Superior. For which property has Marvin forgotten to use an SI unit of measurement?

Illusion [34]

Answer: low temperature

Explanation:-

S.I or M.K.S is a system for defining physical units as meter, kilogram, second, ampere, kelvin or celcius, candela, and mole together with a set of prefixes to indicate multiplication or division by a power of ten for measuring length, mass, time , current, temperature and amount of substance respectively.

Given :

lake length = 563 kilometers = $563\times 10^3m$

High temperature = $76.5^0F$

Low temperature = $-6.3^0C$

annual precipitation =762 mm= $762\times 10^{-3}m$

Thus low temperature in units of Fahrenheit is not an S.I unit of measurement.
