Answer: 5,600 J
Explanation:
Joules = mass x specific heat x temperature change
32 x 4.184 x (54 - 12)
= 133.888 x 42
= 5,623.296
(significant figures => 5,600)

Answer:
B
Explanation:
A toaster turns electrical energy into thermal energy so that it can toast your food.
The equivalence factor that should be used is 1/6.022x10^23. This is called the Avogadro's number. It represents the number of
particles in one mole of any substance. This has the value of 6.022 x 10^23 particles /
mole. <span>This number can be used to
convert the number of atoms or molecules into number of moles. </span>
Answer:
1.6 L
Explanation:
Using Charle's law
Given ,
V₁ = 1.5 L
V₂ = ?
T₁ = 12 °C
T₂ = 32 °C
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (12 + 273.15) K = 285.15 K
T₂ = (32 + 273.15) K = 305.15 K
Using above equation as:
New volume = 1.6 L
