The stress-strain graph for a metallic wire is shown at two different temperature, `T_(1)` and `T_(2)` which temperature is high `T_(1)` or `T_(2)` ?

Explanation

The slope of stress-strain curve with strain axis gives the value of Young's modulus. In the above graph strain is taken along y-axis. Therefore the slope of graph at temperature `T_1` is less than the slope of graph at temperature `T_2`
Now as we know with increase in temperature the value of modulus of elasticity decreases. Therefore temperature`T_1` is greater than temperature `T_2`
