As a result, your body may develop heat cramps, the mildest form of heat-related illness. Signs and symptoms of heat cramps usually include heavy sweating, fatigue, thirst and muscle cramps. Prompt treatment usually prevents heat cramps from progressing to heat exhaustion.
Six additional manmade isotopes are known. Properties: Osmium has a melting point of 3045 +/- 30 Â°C, boiling point of 5027 +/- 100Â°C, specific gravity of 22.57, with a valence usually +3, +4, +6, or +8, but sometimes 0, +1, +2, +5, +7. It is a lustrous blue-white metal. It is very hard and remains brittle even at high temperatures. Osmium has the lowest vapor pressure and highest melting point of the platinum group metals. Although solid osmium is unaffected by air at room temperature, the powder will give off osmium tetroxide, a strong oxidizer, highly toxic, with a characteristic odor (hence the metal's name).
By Anne Marie Helmenstine, Ph.D. Definition: Room temperature is a range of temperatures that denote comfortable habitation for humans.There is no 'exact' room temperature. Room temperature can be any temperature between 20 Â°C and 29 Â°C. 300 K can also be used as room temperature for easy calculations when using absolute temperature.Related Articles.oom temperature can be any temperature between 20 Â°C and 29 Â°C. 300 K can also be used as room temperature for easy calculations when using absolute temperature.
