Question: what is the heat of fusion of ice?
Hypothesis: To get the heat of fusion of ice we need to determine the Energy it takes to melt the ice and also the mass of the ice and determine the heat of fusion. To determine the mass of the ice melted (m) we start by determine the volume of the water generated when the ice melted. This is the difference between the final volume (v2) and the initial volume (v1). Using the density of water (1.0g/mL), this volume can be converted into mass. This concept is shown by the equation [M= (v2-v1) x (1.0g/ml)]. To determine the energy consumed by the melting ice (E), we must determine the energy released by the water to make the ice to melt. This energy can be determined by using the equation to calculate the energy of the temperature changes. The mass of the water releasing heat is determined by multiplying the initial volume (v1) by the density of water (1.0g/mL). The specific heat of water can be obtained from any reliable reference text and is equal to 4.184j/g◦C. the temperature change is the difference between the final temperature (T2) and the initial temperature (T1) of the water. This concept is shown by the equation [E= (v1) x (1.0g/mL) x (4.184J/g°C) x (T2-T1)], and then calculate the heat of fusion of Ice using the equation EM=∆Hf. Plan: To determine the heat of fusion of ice I need a cup of warm water to place the ice cube to calculate the differences of the temperature of the warm water before the ice was add it and after the ice was added it. To take the temperature of the water we need to use a thermometer and make sure it’s in Celsius. To determine the mass, first I need to find the mass of the liquid (water) using a graduated cylinder and then find the mass again after the ice is added and then melted using the same material (graduated cylinder).

April 11, 2011
Abstract: A calorimeter, water at room temperature, ice, and a Pasco GLS Explorer were used in combination with a known value of the latent heat of fusion to create and carry out an experiment to determine the mass of an unknown amount of ice. Using the formula for latent heat of fusion, the mass of the...

Platform balance
Kettle
Milk ice cubes
Stopwatch
Hot Water
Procedure: The copper cup was weighed and its mass was then recorded. The kettle was then used to boil water and this water was poured into the copper cup. The mass of the cup plus the hot water was calculated and recorded. The copper cup was then placed in the...

...Discussions:
1. Why theoretical value different from value obtained?
It may heat loss to the surroundings.
It may have parallax error during taking the reading.
2. Why is usually the cup used in this experiment made of polystyrene?
To prevent heat loss to the surroundings because it is a heat insulator.
3. Why the heat of neutralization has a negative sign?
The reaction gives out heat that results in the increase of...
