Tying marshmallows utilising toothpicks together was difficult about building the model
Building the construct was challenging because of the toothpicks used to connect the marshmallows.
• The Salt Model consists of three layers that can be stacked on top of one another to form a NaCl unit cell.
Using the model in two different orientations is possible if the layers are connected.
• As shown by the salt model, the majority of basic inorganic compounds are composed of ions that interchange endlessly rather than discrete molecules.
Little marshmallows could serve as an analogy for the tiny sodium atoms.

Answer:
The answer to your question is Qt = 15750 cal
Explanation:
Data
mass = m = 150 g
Initial temperature = T1 = 0°C
Final temperature = T2 = 25°C
Process
1.- Calculate the Latent heat of fusion
Latent heat of fusion for water = l = 80 cal/g
Heat = Q
Formula
Q = ml
Substitution
Q = (150)(80)
Simplification and result
Q = 12000 cal
2.- Calculate the Specific heat
Specific heat of water = C = 1 cal/g°C
Formula
Q = mCΔT
Substitution
Q = (150)(1)(25 - 0)
Simplification and result
Q = 3750 cal
3.- Calculate the total heat
Qt = 12000 + 3750
Qt = 15750 cal
Solids and liquids have volumes thatdo not change easily. A gas, on the other hand, has a vol- ume thatchanges to match the volume of its container. The molecules in a gas are very far apart compared with the molecules in a solid or a liquid. The amount of space between the molecules in a gas can change easily.
