The specific heat capacity of iron is 450.5. A 15.5 kg block of iron with an initial temperature of 20 degrees Celsius is heated with 250 J. What will

the final temperature of the iron be?

Explanation:

Given that,

The specific heat capacity of iron is 450.5 J/g°C

The mass of block of iron, m = 15.5 kg

Initial temperature,

Heat required, Q = 250 J

We need to find the final temperature of the iron. The formula for heat required is given by :

So, the final temperature of the iron is .

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.

thermal energy is the answer
