Australia got involved in ww2 for a number of reasons. 1. Australia had no real defence force at the time and if there was an invasion Australia would suffer greatly and therefore relied on Britain heavily for support 2. Australia still had close ties with Britain. As stated in the 1901 constitution Australia's defence and foreign policy was basically that of Britain. 3. Australia was still largely inhabited by Britain's who felt a dire need to protect and help the "mother Country"
What else can I help you with?
What can the state of matter be changed by?
A change in the state of matter occurs when heat energy is added or removed.
What is needed for matter to change it's state?
Energy
How do you change one state of matter to another?
To change one state of matter to another, you need to either add or remove heat energy. For example, to change a solid to a liquid, you would need to add heat energy to melt the solid. Similarly, to change a liquid to a gas, you would need to add heat energy to evaporate the liquid.
When matter undergoes change of state what does it absorb or release?
Energy.
What can changes energy?
Energy can change state of matter. Heat can be used to melt ice.
How does energy help to change the state of matter?
Heat (thermal energy) is the major reason for state change in matter. (Although ambient pressure modifies that at the liquid/vapor boundary.) Basically as energy increases matter moves from solid to liquid to gas to plasma.
How is energy related to the change of state and the forces between molecules?
Energy is related to random and nonrandom states of matter in that all matter and energy tend toward a random state. Nonrandom energy can be directed to keep matter into a desired state, but will ultimately fail.
Can you change a state of matter without increasing or decreasing heat energy?
No.
Which State of matter is easiest to push together?
Gases are the only state of matter that can be compressed.
What causes matter to change its state?
Temperature. Temperature causes matter to change state.
Can change from one state to another?
Matter I think I'm not 100% shure but it say in my book matter in one state often can change to another state by adding or removing thermal energy
Why is energy not considered a state of matter?
Energy is not considered a state of matter because it is a property or characteristic of matter rather than a form of matter itself. Matter is composed of particles (atoms, molecules) that have mass and occupy space, while energy is a measure of the ability to do work or cause change in matter. So, energy and matter are distinct concepts in physics.
