Please help!! If the density of fresh water at 4 degrees Celsius is 1.00g/mL, determine if the following objects will sink or float in water.
1.) A 200 feet (61m) tall pine tree that weighs 11,200 pounds (5,080 kg) and has a density of 0.88g/mL
2.) One gram of lead that has a density of 11.3g/mL
3.) A frozen ice cube of water that has a density of 0.92g/mL
As density of pine tree is less than water it floats.similarly lead sinks and ice floats.
If the density of the object is less than that of water it will float; if the density of the object is greater than that of water it will sink.
pine tree!! that question not mention how long it will float and sink. ice, float at first since lesser density later on it will mixed up to water(combine).
lead always sink. pine tree is the answer, at first float then later on it will sink when the parts of woods gently absorbed water.

To determine if an object will sink or float in water, we need to compare the density of the object with the density of water.
The density of water at 4 degrees Celsius is given as 1.00g/mL. So, any object with a density less than 1.00g/mL will float in water, while an object with a density greater than or equal to 1.00g/mL will sink.
Let's calculate the densities of the objects given:
1.) A 200-feet tall pine tree that weighs 11,200 pounds (5,080 kg) and has a density of 0.88g/mL:
To calculate the density, we need to know the volume of the object. Since we only have the weight and height of the pine tree, we cannot directly calculate its density. We need additional information such as the dimensions of the tree to calculate its volume. Therefore, we cannot determine if the pine tree will sink or float in water.
2.) One gram of lead that has a density of 11.3g/mL:
The density of lead is given as 11.3g/mL, which is higher than the density of water. Therefore, one gram of lead will sink in water.
3.) A frozen ice cube of water that has a density of 0.92g/mL:
The density of the ice cube is given as 0.92g/mL, which is lower than the density of water. Therefore, the ice cube will float in water.
In summary:
- The pine tree's sinking or floating cannot be determined without knowing its volume.
- One gram of lead will sink in water.
- A frozen ice cube of water will float in water.
