Answer:
A. chocolate chips melting
Explanation:
It is a chemical change. cookies will soften and melt slightly as the cookies bake. the change is solid to liquid.
Answer:
0.00420
Explanation:
The equation is Q=mc(T(final)-T(initial), where c is the specific heat, Q is heat supplied, m is mass, T(final) is final temperature and T(initial) is initial temperature (you'll see this written as delta T, which means change in temperature).
2520 = Q
m = 10.0kg; answer choices are in g, not kg, so multiply by 1000 to get m in g; m = 10000 g
Plug in the values you have and solve for c.
2520=(10000)(c)(70-10)
2520=600000c
c=0.0042 j/(gc)
Answer : The distance covered by slow snail in 24 hours is 
Explanation :
As we are given that the a slow snail can travel 2.2 cm in 1 minute. Now we have to calculate the distance covered by slow snail in 24 hours.
First we have to convert 24 hours in minutes.
Conversion used : (1 hour = 60 minutes)
As, 1 hour = 60 minutes
So, 24 hour = 24 × 60 minutes
= 1440 minutes
Now we have to calculate the distance covered by slow snail in 24 hours.
In 1 minute, the distance covered by slow snail = 2.2 cm
In 1440 minute, the distance covered by slow snail = 1440 × 2.2 cm
= 3168 cm
= 
Now we have to convert 'cm' into 'pm'.
Conversion used : 
As, 
So, 
Therefore, the distance covered by slow snail in 24 hours is
