Answer: 2175.68 J heat is required to increase the temperature of 20 grams of water by 26 degrees celsius.
Explanation:
Given: Mass = 20 g
Change in temperature = 
The standard value of specific heat of water is 
Formula used to calculate the heat energy is as follows.
where,
q = heat energy
m = mass of substance
C = specific heat of substance
= change in temperature
Substitute the values into above formula as follows.
Thus, we can conclude that 2175.68 J heat is required to increase the temperature of 20 grams of water by 26 degrees celsius.
Answer:
B) A drawn bow is released, causing an arrow to fly across the field
Explanation:
Potential energy can be thought of as "potential" to do something. For eg, putting a ball on top of hill causes the ball to have the potential to roll down the hill if released. Here the ball converts the potential energy into kinetic energy (energy of motion) to roll down.
Similarly, the bow has been stretched (potential to fly if released), and when its released, it converts the potential energy into kinetic energy.
Answer:
It will be : (in simple terms)
Condensation of hot steam or hot vapor on the cooler skin releases the water's latent heat of vaporization, rapidly raising the temperature of the skin which will result in steam burns.
Hope it helped
All the best!!
