Carbon dioxide is through the plants
Answer:
200 °C
Explanation:
Let’s convert all the temperatures to the same scale, say, Celsius.
<em>Celsius</em>
Water boils at 100 °C, so 200 °C is the temperature of <em>superheated steam</em>.
<em>Fahrenheit
</em>
Water boils at 212 °F, so 200 °F is <em>just below the boiling point of water</em>.
<em>Kelvin
</em>
Standard temperature is 0 °C = 273.15 K. Ice melts at 273.15 K (0 °C), so
200 K is <em>well below the melting point of ice</em>.
C = K – 273.15
C = 200 -273.15 = -73 °C
Thus, 200 °C is the hottest temperature.
When you are doing a experiment, you are testing if your hypothesis is correct or false. If your hypothesis is false, you have to disgard it. If it is correct, you have to do many more parallels, and if they also confirm your hypothesis, your hypothesis can become a theory.

Answer:</h3>
= 19.712 kJoules
<h3>
Explanation:</h3>
- Heat of vaporization refers to the amount of heat required to change a unit mass of a substance from liquid to gaseous state without change in temperature.
To calculate the amount of heat, we use,
Amount of heat = Mass × Heat of vaporization
Q = m×Lv
Given;
Mass of liquid Zinc = 11.2 g
Lv of liquid Zinc = 1.76 kJ/g
Therefore;
Q = 11.2 g × 1.76 kJ/g
= 19.712 kJ
Thus, the amount of heat needed to boil 11.2 g of zinc is 19.712 kilo-joules.
