Answer:
Bad things
Explanation:
Global warming has many terrible effects on people and the earth itself
such as, death, birth defects, asthmea, breathing conditions, increased diseases.
The final temperature of the mixture is closest to 32.5 °C
<h3>Data obtained from the question</h3>
- Mass of warm water (Mᵥᵥ) = 50 g
- Temperature warm water (Tᵥᵥ) = 40 °C
- Mass of cold water (M꜀) = 30 g
- Temperature of cold water (T꜀) = 20 °C
- Specific heat capacity of the water = 4.184 J/gºC
- Equilibrium temperature (Tₑ) =?
<h3>How to determine the equilibrium temperature </h3>
Heat loss = Heat gain
MᵥᵥC(Tᵥᵥ – Tₑ) = M꜀C(Tₑ – M꜀)
50 × 4.184 (40 – Tₑ) = 30 × 4.184(Tₑ – 20)
209.2(40 – Tₑ) = 125.52(Tₑ – 20)
Clear bracket
8368 – 209.2Tₑ = 125.52Tₑ – 2510.4
Collect like terms
8368 + 2510.4 = 125.52Tₑ + 209.2Tₑ
10878.4 = 334.72Tₑ
Divide both side by 334.72
Tₑ = 10878.4 / 334.72
Tₑ = 32.5 °C

Because polymers are covalently bonded material, and metals are metalicly bonded material.
Covalent bonds do not let atoms exchange electrons like metalic bonds do.
