After the ignition net temperature immediately rise to a high temperature, when the flame is fire by the wind, the gas lighter will be ejected from the burning net cover rekindled. Made of net cover metal must use the melting point of ______ (optional "high" or "low"), specific heat ______ (optional "big" or "small") material.
When the absorption or release of the same heat, specific heat capacity is small, increase or decrease the temperature is fast, so the net cover of the metal must have a specific heat capacity of small property
Therefore, the metal must have a high melting point properties;
The temperature of the flame is very high, so the melting point of the metal screen must be higher than that of the flame, so as not to melt
