How much energy must be absorbed by 45.0g of water to increase its temperature from 83 0°C to 303.0°C?
mrs_skeptik [129]

Answer: There will be 41382 J energy must be absorbed by 45.0g of water to increase its temperature from 83.0^{o}C to 303.0^{o}C.

Explanation:

Given: Mass = 45.0 g

Initial temperature = 83.0^{o}C

Final temperature = 303.0^{o}C

Formula used to calculate heat energy is as follows.

q = m \times C \times (T_{2} - T_{1})

where,

q = heat energy

m = mass of substance

C = specific heat = 4.18 J/g^{o}C (here, for water)

T_{1} = initial temperature

T_{2} = final temperature

Substitute the values into above formula as follows.

q = m \times C \times (T_{2} - T_{1})\\= 45.0 g \times 4.18 J/g^{o}C \times (303.0 - 83.0)^{o}C\\= 41382 J

Thus, we can conclude that there will be 41382 J energy must be absorbed by 45.0g of water to increase its temperature from 83.0^{o}C to 303.0^{o}C.

How is a shadow created during a lunar or solar eclipse?
Zepler [3.9K]
However, as a result of the Sun's large angular size, solar<span> illumination is only partially blocked in the outer portion of the Earth's </span>shadow<span>, which is given the name penumbra. A penumbral </span>eclipse<span> occurs when the Moon passes through the Earth's penumbra. The penumbra causes a subtle darkening of the Moon's surface.</span>
