The energy required to raise the temperature of 3 kg of iron from 20° C to 25°C is 6,750 J( Option B)
<u>Explanation:</u>
Given:
Specific Heat capacity of Iron= 0.450 J/ g °C
To Find:
Required Energy to raise the Temperature
Formula:
Amount of energy required is given by the formula,
Q = mC (ΔT)
Solution:
M = mass of the iron in g
So 3 kg = 3000 g
C = specific heat of iron = 0.450 J/ g °C [ from the given table]
ΔT = change in temperature = 25° C - 20°C = 5°C
Plugin the values, we will get,
Q = 3000 g × 0.450 J/ g °C × 5°C
= 6,750 J
So the energy required is 6,750 J.

The rate of product formation by an enzyme-catalyzed reaction would be increased by temperature (until it reaches optimim temperature)
Answer:
The correct answer is option B. From 200K to 400K
Explanation:
Hello!
Let's solve this!
The ideal gas equation is the following PV = nRT
Where the variables are:
P: pressure
T: temperature
V: volume
R: universal constant of ideal gases
n: number of moles
We see in the equation the proportional relationship of volume with temperature.
We deduce that if the volume increases twice, then the temperature increases twice.
The temperature has to be in Kelvin, that's why we chose that answer.
Of the options, the correct answer is option B. From 200K to 400K
