Answer:
3.2 Calories
Explanation:
Here we will use a formula
Heat added in calories = Mass of glass x Increase in temperature x specific heat of glass
As we know that, specific heat is the amount of energy required to raise the temperature of one gram of any substance by 1°C. It has a constant value for every substance and for glass the specific heat is .16 calories/gm
Incorporating the values of mass (m), temperature(T) and specific heat (c) in formula.
calories (small calories) = l.0 g x 20 degrees x .16 calories/gm/°C
= 3.2 calories
Hope it helps:)
Answer:
Positive feedback
Explanation:
If the temperature on Earth starts to lower then a "positive feedback" will start to begin trying to make Earth heat up.
Answer:
1: At temperatures below 542.55 K
2: At temperatures above 660 K
Explanation:
Hello there!
In this case, according to the thermodynamic definition of the Gibbs free energy, it is possible to write the following expression:
Whereas ΔG=0 for the spontaneous transition. In such a way, we proceed as follows:
1:
It means that at temperatures lower than 542.55 K the reaction will be spontaneous.
2:
It means that at temperatures higher than 660 K the reaction will be spontaneous.
Best regards!
Answer:
Commensalism is a symbiotic relationship in which one species benefits while the other species is not affected. One species typically uses the other for a purpose other than food.
