Answer:
A compound
Explanation:
The water is best classified as a compound. When a substance is broken down into elemental composition or units, they are said to be a compound.
- An element is a distinct substance that cannot be split up into simpler substances.
- Compound are substances composed of two or more kinds of atoms joined together in a definite grouping.
- The properties of compounds are distinct and different from those of the individual elements that are combined in its make - up.
- So, the water when broken down to elements is a compound.
Answer:
Explanation:
<em>Given: </em>
P1 = 78.89 ATM
V1 = 12 litres
T1 = 70° C= 343.15 K
V2 = 10 litres
T2 = 95°C= 368.15 K
<em>To find:</em>
P2 = ?
<em>Solution:</em>
Using ideal gas equation,
Since the number of moles & Universal gas constant (R) is constant, the final relation that would be derived between initial & final variables.
<em>(The only unit conversion needed is temperature because it was an addition factor, for other variables it will be cancelled out) </em>
In a microwave oven, microwaves emitted by a small antenna are directed into the cooking compartment, and as they enter, they pass a set of turning metal fan blades.
it used to convey information from one place to another through intervening media,like- Radios and televisions
used in hospitals to produce photograph of bone to check for break or fracture.They can penetrate less dense matter such body tissue and skin.
De Broglie's equation is used to show that photons have both particle and wave nature. photons are quantized packets of energy. the wave nature of photons can be proven as they have a wavelength. the particle nature is given by them having both velocity and mass.
de Broglies equation is;
λ = h / p
where λ - wavelength
h - Planck's constant
p - momentum
substituting the values in the equation
p = h/λ
p = 2.20 x 10⁻²⁷ kgm/s
momentum of photon is 2.20 x 10⁻²⁷ kgm/s
Answer:
Climate is the average weather over a period of time and weather is a short-term change.
Weather is changes in temperature, clouds, rain, or snow
