Answer : The final temperature will be ![66.7^oC](https://tex.z-dn.net/?f=66.7%5EoC)
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
![q_1=-q_2](https://tex.z-dn.net/?f=q_1%3D-q_2)
![m_1\times c_1\times (T_f-T_1)=-m_2\times c_2\times (T_f-T_2)](https://tex.z-dn.net/?f=m_1%5Ctimes%20c_1%5Ctimes%20%28T_f-T_1%29%3D-m_2%5Ctimes%20c_2%5Ctimes%20%28T_f-T_2%29)
where,
= specific heat of ice = ![2.09J/g^oC](https://tex.z-dn.net/?f=2.09J%2Fg%5EoC)
= specific heat of water = ![4.18J/g^oC](https://tex.z-dn.net/?f=4.18J%2Fg%5EoC)
= mass of ice = 15.0 g
= mass of water = 150 g
= final temperature = ?
= initial temperature of ice = ![0.0^oC](https://tex.z-dn.net/?f=0.0%5EoC)
= initial temperature of water = ![70.0^oC](https://tex.z-dn.net/?f=70.0%5EoC)
Now put all the given values in the above formula, we get
![15.0g\times 2.09J/g^oC\times (T_f-0.0)^oC=-150g\times 4.18J/g^oC\times (T_f-70.0)^oC](https://tex.z-dn.net/?f=15.0g%5Ctimes%202.09J%2Fg%5EoC%5Ctimes%20%28T_f-0.0%29%5EoC%3D-150g%5Ctimes%204.18J%2Fg%5EoC%5Ctimes%20%28T_f-70.0%29%5EoC)
![T_f=66.7^oC](https://tex.z-dn.net/?f=T_f%3D66.7%5EoC)
Therefore, the final temperature will be ![66.7^oC](https://tex.z-dn.net/?f=66.7%5EoC)
They will be effected neagtively because of the increase in carbon dioxide with it terrible for plants, animals, and even humans. No trees means no more oxygen for humans.
