True or False- Energy is transferred as heat from a substance at high temperature to a substance at low temperature?
true
In a rigid container as the temperature of a gas decreases the pressure of the gas will decrease true or false?
False
Why aren't properties affected by changes in temperature and pressure?
The properties of all materials are markedly affected by temperature and pressure changes. This is false.
In a flexible containerwhen the temperature of a gas increases the volume of the gas will increase true or false?
true and false it will increase up to the limit that the container can flex then there will be a pressure increase
Air pressure is affected by temperature.?
Yes, air pressure is affected by temperature.When the temperature is higher the air pressure lowers and the weight of the air is lower. When air is warmer the molecules sperate and there are less molecules that can cause pressure.
True or False- Energy is transferred as heat from a substance at high temperature to a substance at low temperature?
true
Is the following true or false temperature is a measure of how hot or cold the substance is?
False. It is a measure of how much enegry a substance has.
True or false temperature is a measure of how hot or cold a substance is?
How hot or cold a substance is the temperature, so a thermometer will measure it.
Is this true or false properties are not affected by changes in temperature and pressure?
false
The pressure of a gas decreased with increasing temperature?
False
Are properties affected by changes in temperature and and pressure?
False
The amount of pressure in a gas is measured in pascals true or false?
True.The amount of gas is determined by its pressure, volume, and temperature. The equation is:PV = nRTwhere:P = pressure, measured in pascals (the SI derived unit of pressure)V = volumen = amount of substance of gas (moles)R = universal gas constantT = temperature
In a rigid container as the temperature of a gas decreases the pressure of the gas will decrease true or false?
False
Is volume is a measure of how much the particles of a substance decrease under pressure?
FALSE
The pressure of gas always increases with increasing temperature?
True.The Ideal Gas Law is PV = nRT, where P is pressure, V is volume, n is the amount of gas, R is the gas constant, and T is temperature. You can see clearly that, all other things being equal, pressure is directly proportional to temperature.
Why aren't properties affected by changes in temperature and pressure?
The properties of all materials are markedly affected by temperature and pressure changes. This is false.
When a substance loses or absorbs energy its temperature can change true or false?
Very true.
