No. Pyrogens act by increasing the temperature, but they do not change the set point in the thalamus.

What is the effect of pyrogen secretion?
Pyrogens are substances that cause the temperature set-point of the body to increase. They cause fever.
At point the liquid is increasing in temperature before reaching boiling point?
Point C
The density of water depends on its?
Pressure and temperature. Increasing the pressure increases the density. Increasing the temperature decreases the density between melting point and 4oC
Does air temperature increase more rapidly than dew point temperature with increasing altitude?
yes
What must happen to a substance to reach it's melting point?
Increasing the temperature up to the melting point.
When a material is melting the temperature?
When a material is melting, the temperature is likely to be increasing. That or the temperature is just above the material's melting/freezing point.
Does increasing the boiling point of water with additives also increase the vapor or steam temperature?
no
How can changing water pressure affect boiling point?
Increasing the pressure increases the boiling temperature
What happends at the melting point?
At the melting point a SOLID turns to a LIQUID. (Increasing temperature). At the same temperature , when a liquid turns to solid it is referred to as FREEZING POINT. NB At the boiling point a LIQUID turns to a GAS. (Increasing temperature). At the same temperature , when a gas turns to liquid it is referred to as CONDENSING POINT. NNB Carbon Dioxide, a gas, moves directly to a solid(dry ice) . This is called the SUBLIMATION POINT.
What is the relationship between a material freezing point and it's melting point?
It is the same thing. A melting point or freezing point is when a "material's" temperature stays the same. Then you can decide whether you want to freeze it or melt it by increasing or lowering the temperature.------Thats how my science teacher tought us.
What is the effect of temperature on the enzymes?
Each enzyme has its' own "perfect" temperature. This varies with the enzyme, the substrate and the environment. In most cases, increasing the temperature above the normal will increase the rate up to a point. Lowering the temperature will slow it down.
How does water affect the melting temperature of rock?
In theory yes: increasing pressure will increase the melting point mostly (not for ice!). In practice: it is hardly noticable, not significant at all, for most solid materials.Pressure increases the melting point of rock. The molecules are packed tighter together and thus take more energy to liquefy.
