How does the amount of a substance affect the rate at which temperature changes?

Chemistry
1 answer:
Katarina [22]3 years ago
5 0
The amount of heat energy transferred (out or in) depends on three factors:1. The capacity of the substance to absorb heat – called the specific heat capacity 2.The amount (moles) of the substances reacting3. The change in temperature
So its not the "amount" of the substance as much as the density of it (the moles). The more dense something is, the slower the rate.

What is the molecular formula of a compound if its emprical formula is NO2 and its molar mass is 138.02 g/mole
Ratling [72]

Answer:

N₃O₆  

Step-by-step explanation:

Data:

EF = NO₂

MM = 138.02 g/mol

Calculations:

EF Mass = (14.01 + 32.00) u

EF Mass = 46.01 u

The molecular formula is an integral multiple of the empirical formula.

MF = (EF)ₙ

  n = MF Mass/EF Mass  

  n = 138.02 u/46.01 u  

  n = 3.000 ≈3

MF = (NO₂)₃

MF = N₃O₆

According to Newton's first law of physics, what will a bowling ball do as it rolls down the bowling alley?
Nitella [24]

Answer:

Because there is no friction, Newton's first law states that the ball should continue to roll. (continue at a constant speed)

Explanation:

Unless acted upon by an unbalanced force, Newton's first law of motion states that an object at rest stays at rest and an object in motion stays in motion with the same speed and direction.
