To raise the temperature of both an equal amount, water would require more energy.
In terms of the energy required to raise the temperature:
iron = 0.45 joules / gram . kelvin
water = 4.2 joules / gram . kelvin
This is known as the specific heat capacity of a material

Would you expect the the pressure exerted by water to be greater or less than the pressure exerted by the same amount of air?
The pressure exerted by water would be greater than the pressure exerted by the same amount of air due to water's higher density. Water molecules are packed closely together, leading to more collisions with the walls of the container and thus a higher pressure compared to air molecules.
In which position would an object have the GREATER amount of potential energy?
An object would have greater potential energy when positioned higher above the ground due to its increased gravitational potential energy.
Which fluid would have the greater viscosity?
Honey would have greater viscosity compared to water. Viscosity refers to a fluid's resistance to flow, and honey is thicker and more resistant to flow than water.
What would a products specific gravity be for it to sink in water?
A product with a specific gravity greater than 1 will sink in water. This means the product is denser than water.
Predict whether a greater amount of energy will be trans ferred as heat between 1 kg of water at 10C and a freezer at -15C or between 1kg of water at 60C and an oven at 65C?
A greater amount of energy will be transferred between 1 kg of water at 60°C and an oven at 65°C. This is because the temperature difference between the water and oven is larger (5°C) compared to the water and freezer (25°C). The rate of heat transfer is directly proportional to the temperature difference.
1 kilogram of water is heated together with 1 kilogram of iron.Which would require greater amount of heat and why?
Iron would require a higher amount of heat due to the fact that it is a metal and has stronger bonds than water does. Water is made up of hydrogen bonds which allow it to heat up quickly.
What would expect to happen to a sidewalk over the course of years when rainwater continues to soak in to concrete and freeze?
If water is allowed to get into a concrete sidewalk and not allowed to drain and it freezes, the expansion of the water/ice as it crystallizes causes the concrete to crack. If more water settles in the crack and freezes, the crack gets bigger. Each year the increase in the size of the crack is greater because a greater amount of water can fit in the crack, and a greater amount of water has a greater amount of expansion when it freezes.
Would expect pressure exerted by water to be greater or less than the pressure exerted by the same amount of mercury?
if you were to immerse yourself under a meter of mercury the pressure experienced would be greater than if you were to immerse yourself under a meter of water.
Can plywood float?
It depends on theplywood density if it is denser then water then you would have to make a shape causing it to displace an equal or greater amount of water in weight for it to float.
Which material would require the least amount of energy to change 1kg from a solid to a liquid ethanol aluminum propane or water?
Water would require the least amount of energy to change 1kg from a solid to a liquid because it has a lower melting point compared to the other materials listed (ethanol, aluminum, propane).
Remove water from gas tank?
A small amount of water such as a couple ounces could be treated with a dose of dry gas with each next few fill ups. A larger amount of water would require removal of the fuel tank to get it all out.
When will a ball filling with water sink?
The ball will sink when the weight of the water inside the ball plus the weight of the ball is greater than the weight of the amount of water that would fit inside the ball.
Air weighs less than water would you expect the pressure exerted by water to be greater or less than the pressure exerted by the same amount of air?
water is more dense than air and it has at
Which type of soil would allow rainwater to reach the well faster and in greater amount?
Sandy soil would allow rainwater to reach the well faster and in greater amount compared to clay soil. Sandy soil has larger particles and better drainage, allowing water to infiltrate more quickly to reach the well. Clay soil has smaller particles and poor drainage, which slows down the movement of water towards the well.
What would a tissue that requires a large amount of energy would have a greater number of?
mitochondria
Which is present in sea water in greater amount between sodium chloride and calsium?
I would say sodium chloride as it is also known as salt-water, calcium is found in chalky cliffs "white cliffs of dover", so near there may be a high amount but sodium chloride would be in greater amounts in the majority of sea water
What can you conclude from seeing identical containers with identical fish in them but with different volume of water in each container?
The one with the greater surface area would have more oxygen available to the fish. The one with the greater volume has a fixed amount of oxygen that can be dissolved in a given amount. The one with the greater surface area has more oxygen available over time.
